Beijing, China – September 3, 2025– On the historic milestone marking the 80th anniversary of the victory of the Chinese People’s War of Resistance Against Japanese Aggression and the World Anti-Fascist War, TOB New Energy held a meaningful group viewing event, resonating in sync with the nation. At 9:00 AM, the company’s conference hall, adorned with fluttering red flags and steeped in solemnity, brought together all employees to witness the grand military parade at Tiananmen Square—a momentous display of historical glory and contemporary strength. This event not only paid profound tribute to the spirit of our predecessors but also injected unifying momentum into the team through a shared experience of “watching together, empathizing together, and striving together,” further anchoring the enterprise’s mission to “align with the nation’s development.” A Symphony of History and Reality: A Transcendent “Spiritual Resonance” Within the conference hall, a large screen live-streamed the magnificent scenes of the parade. As President Xi Jinping delivered his keynote speech, recounting the Chinese nation’s journey from suffering to rejuvenation over the past 80 years, the entire audience sat in rapt attention. Many jotted down key phrases like “remembering history” and “forging the future” in their notebooks. With the first thunderous cannon salute piercing the sky, foot formations, equipment formations, and air echelons paraded past in succession—the steel tide of the air defense missile formation, the silver hair and medals of the veteran honor guard, and the technological edge of the unmanned combat systems. Each frame drew spontaneous applause from the on-site viewers. The Sublimation from “Spectators” to “Strivers” As the military parade concluded on the screen, this 80-year “dialogue across time” deepened TOB New Energy employees’ understanding: so-called “aligning with the nation” is no abstract concept, but rather the integration of individual job value and corporate direction into the historical journey of national rejuvenation. Drawing strength from history and stepping forward with resolve—this, perhaps, is the most precious significance of this collective viewing. We are not only witnesses to history but also builders of the times. Today, we take pride in our motherland together; tomorrow, we will make our motherland proud through our endeavors.

Principle of Cold Isostatic Pressing (CIP) Cold isostatic pressing (CIP) is a process that densifies powders or formed materials under ambient or low temperatures by transmitting isotropic pressure through a fluid (e.g., water or oil). Its core principle is based on Pascal’s Law: the pressure of the fluid in a sealed container is uniformly transmitted in all directions. The specific process involves the following steps: Pressure Transmission Mechanism: The material is encapsulated in a flexible mold (e.g., rubber or plastic) and immersed in a high-pressure vessel filled with fluid (oil or water). An external pressurization system (hydraulic pump) applies pressure to the fluid, which is uniformly transmitted to the material’s surface, achieving three-dimensional isotropic compression. Densification Mechanism: Powder particles undergo plastic deformation or rearrangement under high pressure, closing pores and significantly increasing material density. Due to uniform pressure distribution, internal stresses within the material are consistent, avoiding density gradients caused by traditional uniaxial pressing. Applicable Materials: Suitable for ceramics, metal powders, polymers, and composites, particularly materials sensitive to temperature (e.g., certain solid electrolytes). Comparison with Hot Isostatic Pressing (HIP): CIP operates at ambient temperatures, avoiding phase transitions, grain growth, or chemical reactions induced by high temperatures. However, it cannot achieve sintering densification (requiring subsequent heat treatment). Why is Cold Isostatic Pressing Needed for Solid-State Batteries? CIP is a critical process in solid-state battery manufacturing for the following reasons: Optimization of Solid-Solid Interfaces: A core challenge in solid-state batteries is poor physical contact between solid electrolytes and electrodes (cathode/anode), leading to high interfacial resistance. CIP forces tight adhesion between the electrolyte and electrodes via high pressure, reducing interfacial voids and enhancing ionic transport efficiency. Avoidance of High-Temperature Side Effects: Many solid electrolytes (e.g., sulfides, oxides) are temperature-sensitive. Using hot pressing (e.g., HIP) may induce side reactions (e.g., decomposition of sulfides), grain boundary diffusion, or melting of electrode materials (e.g., lithium metal). CIP operates at ambient temperatures, mitigating these issues. Material Compatibility: Multilayer structures in solid-state batteries (e.g., cathode-electrolyte-anode) require uniform compression during fabrication. CIP’s isotropic pressure ensures uniform compression of multilayer structures, preventing interlayer misalignment or cracking. Typical Application Scenarios Sulfide Solid Electrolytes: High pressure enhances physical contact between the electrolyte and electrodes. Composite of Oxide Electrolytes and Electrodes: For example, densification of LLZO (lithium lanthanum zirconate oxide) with cathode materials (NCM, ...

In recent years, the rapid development of sulfide solid electrolytes—including Li₂S-SiS₂, Li₂S-B₂S₃, Li₂S-P₂S₅, Li(₁₀±₁)MP₂S₁₂(where M = Ge, Si, Sn, Al, or P), and Li₆PS₅X (where X = Cl, Br, I)—has, in particular, partially addressed the drawback of insufficient intrinsic conductivity in solid electrolytes. This progress is exemplified by thio-LISICON-structured sulfides such as Li₁₀GeP₂S₁₂(LGPS), which exhibit an extremely high room-temperature lithium-ion conductivity of 12 mS/cm, surpassing that of liquid electrolytes.   Figure 1(a) shows an all-solid-state lithium battery using a cold-pressed pellet of Li₁₀Ge₂PS₁₂ceramic solid electrolyte powder with a room-temperature electrical conductivity exceeding 5 mS/cm, a LiCoO₂cathode material, a 99% (30Li₂S·70P₂S₅)·1% P₂O₅electrolyte as the anode-side modifier electrolyte, and metallic lithium as the anode. This battery can normally discharge and operate at room temperature to light up an LED lamp. A schematic diagram of the core component structure is shown in Figure 1(b), from which it can be seen that the cathode layer, inorganic solid electrolyte layer, and lithium foil are tightly bonded and pressed together in a mold. The preparation methods and processes of each component will be described in detail below. Figure 1: All-Solid-State Lithium Battery Based on Sulfide Solid Electrolyte 1 Preparation Method of the Cathode Sulfide solid electrolyte powder exhibits a Young's modulus of approximately 20 GPa, along with strong adhesion, high compressibility, and a tendency for plastic deformation. After cold pressing, it demonstrates low grain boundary resistance; thus, it is suitable for direct dry mixing with cathode powder during the preparation of the cathode layer [Fig. 2(a)]. During dry mixing, the conductive agent, sulfide solid electrolyte, and cathode material are simultaneously added to a mortar, followed by manual grinding, or mechanically mixed using a stirrer. It should be noted that the compatibility between different cathode materials and the electrolyte, the applicability of various conductive agents, and the suitability of different cathode coatings need to be evaluated under practical conditions. Figure 2: Preparation Method of the Cathode for All-Solid-State Lithium Batteries Based on Sulfide Solid Electrolytes For large-scale roll-to-roll (R2R) fabrication of sulfide batteries, the wet coating process [Fig. 2(b)] may be more suitable for scaling up. This is because polymer binders and solvents are required to prepare thin-film electrolyte and electrode layers with the mechanical properties needed for high-throughput R2R processes. Additionally, the presence of flexible polymers in the electrolyte/electrode can effectively buffer the stress and strain generated during repeated charge-discharge cycles, mitigating issues such as crack formation and particle detachment.   However, the following considerations are necessary during preparation: ① The polymer binder should be di...

On July 8, Xiamen TOB New Energy Technology Co., Ltd. welcomed another group of customers for equipment acceptance. The newly accepted equipment is dedicated to laboratory research on lithium-ion coin cell batteries, including glove boxes, punching machines, and crimping machines. This acceptance process, led by Ailsa Zheng, Head of Sales Team 3, with full technical support, concluded with unanimous confirmation that the equipment met requirements through on-site operation and data testing. 1. High-Purity Glove Box: Creating a "Water-Oxygen-Free" Microenvironment Core materials for coin cell batteries (e.g., electrolytes, electrode active materials) are highly sensitive to water and oxygen—trace impurities can lead to capacity decay, shortened cycle life, or even battery failure. Therefore, laboratory-grade glove boxes must control water and oxygen content inside the box below ppm (parts per million) levels. These boxes support full-process operations, including electrode sheet preparation, battery assembly, and vacuum electrolyte injection. Equipped with visual observation windows and anti-static operating gloves, they further ensure the accuracy and safety of R&D personnel’s operations. 2. Electric Sealing Machine Powered by electricity, this machine TOB-DF-160 saves operational effort and can be configured with different molds for tasks such as dry powder pressing, wet powder pressing, molding, and riveting. Mold Configuration: Standard molds are designed for 20-series coin cell batteries. By replacing mold accessories, it can also seal other coin cell batteries (e.g., 2450, 2430) and accommodate mold removal. 3. High-Precision Electrode Sheet Punching Machine: Ensuring "Thin yet Standard" Electrodes Electrode sheets for coin cell batteries typically measure only 0.01–0.03 mm in thickness (about 1/5 the diameter of a human hair). Their thickness consistency and burr control directly impact battery internal resistance and energy density. Traditional punching machines often suffer from issues like edge burrs and large thickness deviations, leading to increased self-discharge rates. This machine TOB-CP60 features an upper punch die guided by high-precision rails, enabling high punching accuracy with no burrs, edge defects, or pressure marks. It can punch various battery materials with thicknesses ranging from 0.005 to 0.5 mm.

The electrodes of Lithium-ion Batteries (LIBs) are primarily composed of electrochemically active electrode materials, conductive additives, binders, current collectors, and other components. Among these, binders serve as a critical component of LIBs electrodes. Binders can firmly adhere active materials and conductive materials to the current collector, forming a complete electrode structure. They prevent the detachment or exfoliation of active materials during charging and discharging processes, while also uniformly dispersing active materials and conductive agents. This enables the formation of a favorable electron and ion transport network, thereby facilitating efficient transport of electrons and lithium ions. Currently, substances used as electrode binders include poly(vinylidene fluoride) (PVDF), carboxymethyl cellulose (CMC), styrene-butadiene rubber (SBR), poly(vinyl pyrrolidone) (PVP), poly(methyl methacrylate) (PMMA), poly(acrylonitrile) (PAN), poly(acrylic acid) (PAA), poly(vinyl alcohol) (PVA), sodium alginate (Alg), β-cyclodextrin polymer (β-CDp), polypropylene emulsion (LA132), poly(tetrafluoroethylene) (PTFE), and so on, as well as functionalized derivatives of the above-mentioned polymers or copolymers formed by monomers. In lithium-ion battery (LIB) electrodes, the ideal binder performance should include: (1) chemical and electrochemical stability in a given electrode/electrolyte system, resistance to electrolyte corrosion, and no occurrence of redox reactions within the operating voltage range; (2) It should exhibit good solubility, with fast dissolution rate and high solubility in solvents, and the required solvents should be safe, environmentally friendly, and non-toxic, with water-based solvents being preferred; (3) It should have moderate viscosity to facilitate slurry mixing and maintain slurry stability, while also possessing strong adhesion, resulting in electrodes with high peeling strength, excellent mechanical properties, and low binder usage; (4) It should demonstrate good flexibility to tolerate bending during electrode handling and volume changes of active material particles during the charge-discharge cycles of LIBs; (5) It should be capable of forming an ideal conductive network with conductive agents, leading to electrodes with good electrical conductivity and lithium ion conduction capability; (6) It should be widely available and low-cost. This paper summarizes recent research achievements related to LIB electrode binders, with a focus on introducing the adhesion mechanisms of binders in electrodes and the commonly used oil-based and water-based binders in current LIB electrodes. 1 Adhesion Mechanism of Binders in Lithium-Ion Battery Electrodes The production process of LIB electrodes typically involves four steps: mixing various materials (including electrode active materials) in a solvent to form a battery slurry, coating the slurry onto a current collector, drying, and rolling. It is generally believed that...
