Factory acceptance testing, on-site installation, commissioning, operator training, and after-sales support were formalized as standard processes and deployed with complete-line projects at customer sites in India, Europe, and North America, improving control over delivery schedules and quality for intercontinental projects.
  5. Process support was moved to an earlier project stage. The company provided customers with process-window parameters, line layouts, and equipment selection plans, supporting universities and research institutes in progressing from laboratory formulation validation to pilot-scale production and strengthening the company's technical role during early-stage process development.
  6. The export supply chain and manufacturing system supported parallel deliveries across multiple locations. The Xiamen manufacturing base's component supply chain, incoming inspection processes, and manufacturing documentation—including equipment specifications, commissioning procedures, and operating manuals—ensured consistent equipment specifications and spare-parts supply across intercontinental deliveries.

R&D Expansion and the First Overseas Pilot-Line Delivery

TOB Established Its In-House Technology Research and Development Team

In 2014, TOB NEW ENERGY expanded its in-house technical and R&D teams and upgraded its factory production equipment to meet customer requirements. During the year, it delivered its first complete overseas pilot line, advancing from individual equipment supply to complete-line delivery.

  1. The company's “TB” trademark was registered in December 2014, establishing a proprietary brand identity for consistent use in overseas markets.
  2. The company expanded its in-house technical and R&D teams by establishing independent R&D and process engineering functions in Xiamen and adding positions in electrode processes, mechanical design, electrical control, and automation. Key members had previously held technical and management positions at battery and materials companies in China and abroad. R&D transitioned from a production-dependent function to an independent organizational unit.
  3. The company defined its in-house development priorities and established a path for commercializing R&D results. It conducted proprietary design work for key electrode manufacturing and cell assembly processes, developing integrated process and equipment capabilities for mixing, coating, calendering, slitting, and winding/stacking. R&D results were applied directly to customer projects, shortening the cycle from solution design to equipment delivery.
  4. The company upgraded production equipment at its Xiamen manufacturing base, including precision machining, assembly, and commissioning stations. It expanded complete-machine commissioning and in-house validation capacity, reducing line manufacturing and acceptance cycles and increasing the number of complete-line projects that could be undertaken concurrently.
  5. The company delivered its first complete overseas pilot line to India, covering engineering design, manufacturing, factory acceptance testing, shipment, on-site installation and commissioning, and operator training. This established a replicable model for overseas complete-line delivery and directly enabled laboratory-line and pilot-line supply across three continents in 2015.
  6. The international customer portfolio advanced during the year, with key customers including 3M (USA), IIT Delhi, IIT Bombay, and PT ASTRA OTOPARTS. Customers included a major North American materials company, leading Indian institutes of technology, and a Southeast Asian manufacturing group, while customer profiles and project complexity both increased.
  7. R&D and manufacturing formed a closed-loop system. The in-house R&D team worked directly with the manufacturing system to establish an iterative cycle of R&D equipment models, validation at customer sites, and batch manufacturing, providing the organizational and capability foundation for product-line expansion and subsequent scaled delivery.
2013

Era 01 · 2002–2011

A Decade of Battery Engineering by the Founding Team

Before the company was established, the founding team was already designing cells and building battery factories. Beginning with pouch-cell materials in 2002, the team went on to work with cylindrical and large prismatic aluminium-case cells. The process know-how accumulated over this decade, together with patents that have been widely cited, laid the foundation for TOB NEW ENERGY's subsequent development. The cumulative number of customers with completed transactions exceeded 1,000.

2011

Building a Battery Equipment Factory: From In-House Machines to Full Production-Line Capabilities

Continuing the shift towards equipment development that began in 2010, the founding team started building a battery equipment manufacturing factory in 2011. Equipment previously developed in-house for the team's own cell R&D was standardised into complete, deliverable systems, with assembly, commissioning and process validation organised across three product lines: pouch, prismatic and cylindrical cells. Cell design, manufacturing processes and equipment engineering converged during the year, providing TOB NEW ENERGY with a complete product portfolio and engineering foundation ahead of its establishment in 2012.

  1. Construction began on a battery equipment manufacturing factory, with assembly, commissioning and trial-operation areas organised around three product lines: pouch, prismatic and cylindrical cells. This created a complete processing–assembly–commissioning–process validation loop and transformed the equipment business from an R&D initiative into a physical manufacturing operation.
  2. Experimental equipment developed in-house over the previous eight years for the team's own cell R&D was standardised into a series of machine models covering the principal processes of mixing, coating, calendering, slitting, winding and stacking, packaging, electrolyte filling, formation, and sorting and inspection. Drawings, bills of materials and work instructions were also standardised.
  3. A pre-delivery trial-operation and process-validation system was established. Each machine first completed a small production run in-house using real slurry and electrode sheets; delivery proceeded only after throughput and stability were confirmed, raising the delivery standard from “able to operate” to “able to produce reliably.”
  4. The process and equipment teams began working as one, creating a development workflow in which process requirements defined equipment specifications and equipment precision, in turn, expanded the process window. Design standards for modularity, format changeover and ease of maintenance were also established and later became the common design language across the company's equipment portfolio.
  5. The team advanced in-house production of core components for key processes including tension control, tab welding, packaging and sealing, electrolyte metering, and cell sorting. This reduced reliance on purchased standard components and enabled the equipment to accommodate different customer cell specifications and process routes.
  6. Mass-production experience from the three stages—pouch cells (2002–2004), cylindrical cells (2005–2006) and large prismatic aluminium-case cells (2007)—was used as an input for equipment design. Leakage, swelling, consistency and temperature-rise issues previously encountered on the team's own production lines were incorporated into equipment design conditions and acceptance standards.
  7. The team developed the concept of complete small-scale laboratory lines for battery companies, expanding from individual machines to laboratory-line combinations configured around the cell development process. This formed the prototype for the later laboratory-line and pilot-line businesses.
  8. Mechanical, electrical, process and after-sales functions were expanded, and delivery procedures were established for equipment installation, commissioning and operator training. The team evolved from “engineers who understood cells” into “an equipment engineering team that understood production lines.”
  9. Significance: In 2011, the team established the pathway from cell processes to equipment manufacturing. When TOB NEW ENERGY was founded in 2012, the team therefore possessed both an understanding of battery processes and equipment manufacturing capabilities.
2010

Strategic Shift to Battery Equipment: Systematic Development of Laboratory Equipment

TOB's Large Prismatic Cell Engineering and the Path to Xiamen

In 2010, the team's focus shifted from cell manufacturing to battery equipment development. It systematically developed laboratory equipment for pouch, prismatic and cylindrical cells, configuring expandable equipment combinations around the cell manufacturing process. Meanwhile, two patented technologies developed during the cell-design stage—a high-power lithium-ion cell and a pressure-adjustable safety valve—continued to be cited by subsequent patents and became important inputs for equipment design.

  1. Shift in focus: R&D resources were redirected from cell product lines to battery equipment development, repositioning the team from a cell manufacturer to a supplier of battery processes and equipment.
  2. Laboratory equipment was developed for pouch, prismatic and cylindrical cell formats. Configured as expandable combinations around the cell manufacturing process—mixing, coating, calendering, slitting, winding and stacking, packaging, electrolyte filling, formation, and capacity grading and inspection—the equipment could be expanded process by process from laboratory scale to pilot and mass production as the process matured.
  3. Two patents created during the team's cell-design stage—the high-power lithium-ion cell (CN101425605B) and the pressure-adjustable safety valve for lithium-ion cells (CN101399324B)—continue to be cited by subsequent patents.
  4. Issue lists covering pouch-cell sealing leakage and gas swelling in 2003, cylindrical-cell consistency and high-rate temperature rise in 2005–2006, and electrolyte filling and wetting for large aluminium-case cells in 2007 were converted item by item into technical specifications and acceptance criteria for laboratory equipment.
  5. The equipment platforms for all three cell formats were unified, allowing the same machine frame and control system to accommodate pouch, prismatic and cylindrical cells. This reduced format-change costs and enabled customers to validate multiple cell formats with one set of laboratory equipment.
  6. A process-adaptation method for equipment was established: process windows were first validated on the team's own trial-production line using self-built or modified equipment, after which the machine design was finalised for delivery, with equipment and process parameters handed over together.
  7. Internal mechanical-design and electrical-control capabilities were developed, creating an independent development chain from cell processes to equipment structures and from equipment structures to control logic, without relying on generic machines from external equipment suppliers.
  8. Market entry approach: Complete equipment and process solutions were offered to domestic battery companies for laboratory and trial-production applications, differentiated by the team's positioning as “an equipment supplier with hands-on cell manufacturing experience.”
  9. Significance: Equipment development extended the team's capabilities from cells to production lines, directly leading to the construction of the equipment factory in 2011 and the establishment of TOB NEW ENERGY in 2012.
2009

Cylindrical Batteries for E-Cigarettes and Bluetooth Headsets Enter Mass Production

In 2009, the team completed the transition to mass production for two small cylindrical batteries developed in 2008. Daily output of cylindrical e-cigarette batteries reached 100,000 units, while Bluetooth-headset batteries achieved stable small-batch production of 10,000 units per day. Small cylindrical batteries became the year's principal product focus, and the team established the manufacturing and quality systems required for production at this scale.

  1. Cylindrical e-cigarette batteries entered mass production, reaching daily output of 100,000 units and becoming the year's largest product line by volume.
  2. Bluetooth-headset batteries entered small-batch mass production at 10,000 units per day, serving demand from miniature consumer electronics such as mono Bluetooth headsets.
  3. Production-line takt time was reconfigured around the targeted daily production scale. Winding, sealing, electrolyte filling, formation and sorting workstations were separated according to bottleneck processes, and line capacity was progressively increased through equipment-count planning and process balancing.
  4. A consistency-control system was established for small cylindrical batteries: online control of electrode dimensions and winding tension, precise electrolyte metering, capacity and internal-resistance grading after formation and capacity grading, and self-discharge screening to eliminate latent micro-short-circuit risks. Mass-production quality became statistically manageable and traceable.
  5. Three manufacturing challenges for small cylindrical batteries were resolved: sealing leakage through optimisation of the seal structure and gasket fit; tab welding through consistent miniature weld spots; and control of micro-volume electrolyte filling and wetting. This established the process foundation for higher subsequent output.
  6. Dedicated equipment was built in-house for small cylindrical batteries, including automatic winding, automatic sealing, automatic electrolyte filling, and automatic inspection and sorting machines. Developed in response to real mass-production requirements, these machines became direct prototypes for the later battery equipment business.
  7. Market applications expanded: e-cigarettes and Bluetooth headsets were both fast-growing consumer-electronics categories at the time. Their differing requirements for battery size, capacity and safety led the team to define cell specifications and safety designs separately for each application scenario.
  8. Mass-production process specifications and operating standards were established for small cylindrical batteries, converting parameters developed during the R&D stage into replicable manufacturing documentation to support subsequent production-line replication.
  9. Significance: Mass-production experience at this scale gave the team its first complete command of the interrelationship among product, process, equipment and quality, providing all of the real-production inputs needed for the shift to equipment development in 2010.
2008

Developing Batteries for E-Cigarettes and Bluetooth Headsets as Two Cell-Design Patents Take Shape

TOB Developing Batteries for E-Cigarettes and Bluetooth Headsets

In 2008, the team developed small cylindrical batteries for two emerging consumer-electronics applications—e-cigarettes and Bluetooth headsets—and researched dedicated production equipment for them. During the same period, two cell-design patents, covering a high-power lithium-ion cell and a pressure-adjustable safety valve for lithium-ion cells, entered the application process in succession, systematically consolidating the team's cell-structure design capabilities.

  1. Development of cylindrical e-cigarette batteries: The team improved high-current discharge capability and cycle stability in a miniature cylindrical format to meet the pulse-discharge characteristics of e-cigarettes, while addressing consistency and safety in small cells.
  2. Development of Bluetooth-headset batteries: Cell design and packaging structure were optimised for miniaturisation, low self-discharge and long storage life, balancing capacity, size and safety within an extremely limited space.
  3. Dedicated equipment was researched for the two types of small cylindrical batteries. Adapted machine models were developed for miniature winding, precision sealing, micro-volume electrolyte filling, and automatic inspection and sorting, translating cell-design requirements for dimensional precision into requirements for equipment positioning repeatability.
  4. CN101425605B, covering a high-power lithium-ion cell using lithium nickel cobalt manganese oxide, was filed on 1 November 2007. This cell-design patent has been cited 17 times to date.
  5. CN101399324B, covering a pressure-adjustable safety valve for lithium-ion cells, was filed on 25 September 2008 and has been cited 13 times to date. The patent complemented the large aluminium-case battery developed in 2007.
  6. Experience from developing small cylindrical batteries was applied back into equipment design. Requirements for precision and stability in sealing, welding and electrolyte filling were implemented item by item in equipment structures, establishing the practice of “first make the cell, then make the equipment.”
  7. Market application: Small cylindrical batteries entered the consumer-electronics supply chain, with development and validation organised around device manufacturers' requirements for size, capacity and safety.
  8. Process system: A development workflow was established from material evaluation and cell design through sample trial production and reliability validation. Cell-design experience and patented technologies were codified as the team's internal design standards.
  9. Significance: Small cylindrical batteries opened a new market direction in consumer electronics, while the equipment research and patent portfolio simultaneously laid the groundwork for mass production the following year and the shift to the equipment business two years later.
2007

Developing Large Prismatic Aluminium-Case Batteries with Individual Cell Capacity of 100 Ah

In 2007, the team shifted from small consumer batteries to the development of large prismatic aluminium-case batteries, achieving an individual cell capacity of 100 Ah—a relatively high-capacity specification that could be developed in the market at the time. The material systems covered both NCM111 and lithium iron phosphate (LFP), with natural and artificial graphite used for the anode. Individual cell energy density reached 200 Wh/kg, and the target markets were electric motorcycles and electric logistics vehicles.

  1. Large prismatic aluminium-case batteries were developed with an individual cell capacity of 100 Ah, a relatively high-capacity specification that could be developed in the 2007 market. This extended the team's product portfolio from consumer batteries into traction batteries.
  2. Two material systems were advanced in parallel: the NCM111 ternary route for energy-density and power requirements, and the lithium iron phosphate (LFP) route for cycle life and safety. The anode used a blend of natural and artificial graphite to balance cost and rate performance.
  3. Individual cell energy density reached 200 Wh/kg.
  4. To manage internal pressure and gas generation in large prismatic aluminium-case batteries, the team designed a pressure-adjustable safety valve (CN101399324B, filed in September 2008), providing a controlled pressure-release path under abnormal operating conditions.
  5. Manufacturing challenges unique to large-capacity cells were overcome: thickness uniformity in wide-web electrode coating; winding and assembly of large electrode assemblies; control of electrolyte volume and wetting time; and gas generation and shaping during formation. None of these issues had arisen with the earlier small batteries.
  6. Corresponding equipment was built or modified in-house for the 100 Ah large-format cells, including wide-web coating, large-diameter winding, case welding, high-volume electrolyte filling and formation equipment. Equipment capabilities were scaled in step with cell dimensions.
  7. Cell-design capabilities were extended by transferring the design methods used for high-rate cells in 2006—including tab structure, current collectors and current distribution—to large-capacity cells, improving temperature rise and uniformity during high-current charging and discharging.
  8. Target market and product definition: Individual cell specifications and pack configurations were defined for electric motorcycles and electric logistics vehicles. For the first time, the team designed cells around vehicle applications rather than consumer-electronics applications.
  9. Significance: Development of the 100 Ah large aluminium-case battery added the large prismatic route to the team's existing pouch and cylindrical formats, creating a parallel technical portfolio for consumer and traction applications.
2006

Cylindrical Batteries Enter Volume Production: Daily Capacity Reaches the Tens of Thousands and a 30C High-Rate Design Is Realised

TOB's First High-Rate Lithium-Ion Cell Patent and Move into Cylindrical Cells

In 2006, cylindrical batteries moved from the laboratory into mass production. Within six months, daily output increased from 1,000 to 30,000 units, while manufacturing yield remained above 90%. During the same period, the team increased the cell discharge rate to 30C, kept battery surface temperature below 70 °C, and filed a national invention-design patent. Cylindrical batteries began entering supply chains for applications including power tools and laptop computers.

  1. CN1819321A, “A High-Rate Lithium-Ion Battery,” was filed on 6 March 2006, with Mr. Huang named as a co-inventor.
  2. The application disclosed measured discharge curves at 7C, 10C and 12C in eight figures.
  3. The patent application has since been cited by 11 subsequent patents.
  4. Cylindrical batteries moved from the laboratory into mass production, with daily output increasing from 1,000 units at the laboratory stage to 30,000 units within six months. Manufacturing yield remained above 90%.
  5. Cell rate capability reached 30C, while battery surface temperature was kept below 70 °C during high-rate discharge.
  6. A paper on battery rate design was presented at an international forum, sharing the design methods and measured data for high-rate cells.
  7. The mass-production line was built and brought into stable operation. Winding, sealing, electrolyte filling, formation and sorting were separated into distinct processes; capacity was ramped up through equipment-count planning, process balancing and tooling standardisation, with yield control implemented at every process step.
  8. Cylindrical batteries entered supply chains for applications including power tools and laptop computers, making the team a battery supplier for these markets. Their high-rate capability directly matched the high-current requirements of power tools.
  9. Earlier work had focused on pouch-cell material development (2002–2006); the team then moved into cylindrical cells, completing the transition in technical route from pouch to cylindrical formats.
  10. Significance: The combination of daily capacity in the tens of thousands, 30C high-rate performance and mass-production yield gave the team large-scale consumer-battery manufacturing capabilities and established a reusable production-line and quality-management model for subsequent product lines.
2005

Cylindrical Cell Development: Four Models and Energy Density of 170 Wh/kg

In 2005, the team shifted from pouch to cylindrical cells, developing four models—14500, 14650, 18650 and 26650. The material systems combined NCM111 and lithium iron phosphate (LFP) with natural and artificial graphite anodes, achieving an energy density of 170 Wh/kg. At the same time, Sanyo, Panasonic, Samsung, E-One Moli Energy (Molicel), and China's BAK Battery and Lishen were all advancing cylindrical-cell technologies. In this field, the team resolved three critical issues—sealing leakage, energy density and consistency—and met mass-production requirements.

  1. Cylindrical batteries were developed in four models—14500, 14650, 18650 and 26650—creating a cylindrical product range from small to medium sizes.
  2. The material systems followed both NCM111 and lithium iron phosphate (LFP) routes, with natural and artificial graphite used for the anode. Energy density reached 170 Wh/kg.
  3. Sealing leakage was a key focus. The team worked simultaneously on seal structure, gasket fit, and the pressure–time curve of the sealing equipment, and established a seal-integrity testing method that moved leakage control from post-production sorting into the manufacturing process itself.
  4. Consistency was improved by controlling electrode dimensional accuracy, winding tension, electrolyte volume and formation conditions, narrowing the distribution of capacity, internal resistance and self-discharge among cells of the same specification to levels suitable for mass production.
  5. Mass-production requirements were met: The process was finalised for stable batch production, and the production line, tooling and standards were prepared for the capacity ramp-up in 2006.
  6. Competitive landscape: The principal international cylindrical-battery manufacturers at the time were Sanyo, then the market-share leader, Panasonic, Samsung and E-One Moli Energy (Molicel); Chinese peers included BAK Battery and Lishen. The team differentiated itself through multi-model coverage and flexibility in material systems.
  7. Equipment capabilities: The team built and modified equipment in-house for cylindrical-cell winding, sealing and electrolyte filling, incorporating process-parameter requirements directly into machine design. This “process–equipment integration” approach continued to be used thereafter.
  8. Technical-route expansion: Cylindrical cells were added to the pouch-cell work of 2002–2004, giving the team command of the materials, structures and manufacturing processes for two mainstream cell formats.
  9. Significance: Cylindrical-cell development in 2005 was a crucial step in the team's transition from a single format to multiple formats. The energy density of 170 Wh/kg and finalisation of the mass-production process provided the direct foundation for large-scale production the following year.
2004

Large-Scale Pouch-Cell Production: Daily Capacity Rises from Hundreds to 30,000 Units

In 2004, pouch batteries moved from laboratory development into large-scale production. Within six months, daily output increased from 100 to 30,000 units, manufacturing yield remained above 90%, and supply capacity ranked among the top three in the pouch-battery market that year.

  1. Pouch batteries entered large-scale production. Starting at 100 units per day, output increased to 30,000 units per day within six months, with manufacturing yield exceeding 90%.
  2. Supply capacity ranked among the top three in the 2004 pouch-battery market, transforming the team from a technology developer into a supplier capable of large-scale delivery.
  3. A mass-production plant and production line were built. Dry rooms and cleanrooms were planned around pouch-battery moisture and cleanliness requirements, and a complete production line was laid out for electrode fabrication, packaging, electrolyte filling, formation, and capacity grading and inspection. Material-flow routes were designed to shorten waiting times between processes.
  4. Yield-assurance system: Failure modes including sealing leakage, swelling and abnormal internal resistance were broken down process by process. A three-tier inspection system covering incoming materials, in-process production and finished-product sampling was established, together with process-yield statistics and an abnormality-feedback mechanism.
  5. Process finalisation: The seal-integrity and gas-generation-control methods validated in the laboratory in 2003 were codified into mass-production process parameters and operating standards, making the process replicable and transferable.
  6. Equipment was built and modified in-house for pouch-cell mass production, including stacking/winding, heat sealing, electrolyte filling, vacuum packaging and inspection equipment. Equipment capacity increased in step with production-line takt time, further deepening the team's understanding of machine structures.
  7. Market applications: Pouch batteries entered the consumer-electronics supply chain for mobile phones, digital products and other applications, with product development and validation organised around device manufacturers' requirements for thickness, capacity and safety.
  8. Team and systems: Production-line management, process engineering and quality functions were progressively separated, establishing an organisational model spanning sample trial production through batch delivery.
  9. Significance: The cost, yield and delivery experience gained through mass production became the platform the team later replicated rapidly across cylindrical and large prismatic cells. It also became the source of the equipment business's practical understanding of how production lines operate successfully.
2003

Laboratory Development of Pouch Batteries: Overcoming Sealing Leakage and Gas Swelling

In 2003, the team developed pouch batteries at laboratory scale, focusing on two process challenges that constrained the pouch route: sealing leakage and gas swelling. In the process, it also developed equipment capabilities in packaging, electrolyte filling and inspection. ATL (Amperex Technology Limited) and TCL Hyperpower were advancing pouch technology during the same period, and the team's technical level in this field reached mass-production requirements.

  1. Pouch batteries were developed at laboratory scale, progressively establishing the complete process from material evaluation and electrode fabrication through packaging and formation.
  2. Sealing leakage was resolved through systematic experiments on the process window for heat-sealing temperature, pressure and time, as well as the seal structure, sealing-layer thickness and sealing method around the tabs. Seal-integrity and insulation testing methods were established, enabling leakage to be traced to specific process parameters.
  3. Gas swelling was addressed through moisture control in materials and electrolyte, analysis of the gas-generation mechanism during formation, and the secondary-sealing degassing process. Dry-environment control, formation-process optimisation, and vacuum degassing and packaging suppressed swelling while maintaining stable cell appearance and thickness.
  4. Equipment capabilities: To resolve sealing and swelling issues, the team built and modified heat-sealing, vacuum-packaging, electrolyte-filling and seal-integrity-testing equipment in-house. This converted process problem-solving into equipment-development experience and marked the origin of the team's later decision to make equipment its core business.
  5. Industry context: ATL (Amperex Technology Limited) and TCL Hyperpower were principal drivers of pouch-battery development during the same period. The team completed validation of key pouch-battery technologies within a similar technical tier and timeframe.
  6. The technology reached mass-production requirements: The process was finalised and repeatability was validated, providing the process basis for construction of the volume-production line in 2004.
  7. Material-system expertise: Evaluation methods and matching experience were established for cathode and anode materials, separators, electrolyte and aluminium-plastic-film packaging materials, creating an understanding that “materials define the performance ceiling, while the process determines whether it can be achieved.”
  8. Significance: The two process breakthroughs in 2003 moved the pouch route from feasibility validation to manufacturability, giving the team its first complete technical chain spanning materials, processes and equipment.
2002
