GRANTED UTILITY MODEL · CN215432708U · ACTIVE Lithium Battery Electrode Cutting Machine with Integrated Cleaning Structure A vacuum-fed battery sheet cutting machine whose slices drop straight into an ultrasonic cleaning cavity and leave the machine already clean - cutting and cleaning in one continuous flow. Full specification and drawings: CN215432708U on Google Patents Reviewed by Dany Huang, Ph.D., Founder & CEO, TOB NEW ENERGY | Last updated: 11 September 2026 Cutting battery sheets into slices is only half the job - the freshly cut pieces then have to be cleaned. The specification of CN215432708U describes what that meant on the production floor before this patent: the cutting machines in use could not clean the cut pieces themselves, so a separate cleaning machine had to stand next to each cutting machine. Machines piled together, the work area stayed dirty, and the footprint grew. CN215432708U, filed on 26 August 2021 and granted on 7 January 2022, closes that gap inside a single machine. Stacked sheets are picked up one by one by a vacuum carriage, conveyed to a set of tungsten-carbide vertical cutters, and the slices then fall directly into an ultrasonic cleaning cavity built into the same body - clean slices come out of one continuous flow.

GRANTED UTILITY MODEL · CN215430810U · ACTIVE Lithium Battery Electrode Roller Press with Independent Two-Stage Compaction Two separately controlled pressing stages, inline heating before the final nip, and continuous magnetic debris capture - the calendering patent behind TOB roller presses. Full specification and drawings: CN215430810U on Google Patents Reviewed by Dr. Dany Huang, Chief Technologist, TOB NEW ENERGY | Last updated: 10 September 2026 Calendering is the step where electrode quality is either locked in or lost. Press too lightly and the coating stays porous, with poor particle-to-particle contact. Press too hard and you destroy the capacity you just finished coating on - the patent states the mechanism plainly: excessive compaction density forces active material particles into contact too tightly, polarisation rises, working voltage drops, and the cell delivers less capacity than the coating weight promised. Between those two failure modes there is a narrow window, and a press that applies one fixed pressure through one fixed nip cannot reliably stay inside it. CN215430810U, filed on 1 September 2021, splits compaction into two independently controlled stages, adds heat before the final nip, and - unusually - cleans itself while running.

GRANTED UTILITY MODEL · CN215429971U · ACTIVE Laboratory-Scale Battery Electrode Coating Machine A complete coating line - unwinder, coating station, dryer, rewinder and an inline slurry mixer - integrated in one compact, portable housing for laboratory battery work. Full specification and drawings: CN215429971U on Google Patents Electrode coating sets the capacity, consistency and safety of a lithium cell: slurry must be spread evenly over the current collector and its solvent dried out, and coating quality flows directly into capacity, internal resistance, cycle life and safety. Production coaters do this well at scale - but they are large, built for batch production, and poorly suited to the coating work a laboratory actually needs. CN215429971U, filed on 9 September 2021, answers that gap with a different geometry: instead of shrinking a production line, it packs the whole coating function - unwinder, coating station, dryer, rewinder and slurry mixer - into a single small housing that sits on a bench and can be carried.

INVENTION · PUBLISHED APPLICATION · CN1819321A CN1819321A - Lithium Ion Battery With High Multiplying Factor A 2006 electrode-chemistry route to 12-15C sustained discharge - by dry-powder premixing of active material and conductive agent before the slurry is ever made. Co-invented by TOB NEW ENERGY's chief technologist. In 2006, a commercial lithium-ion cell could typically sustain 1-3C continuous discharge. Power tools needed 5C. Flying models needed 7C. RC model aircraft needed 12C and above. That gap is why nickel-cadmium and nickel-metal-hydride packs - heavier, bulkier, burdened by memory effect - still dominated the high-drain market. Patent application CN1819321A, filed on 6 March 2006, addressed that gap without exotic materials. It reached 12-15C using conventional LiCoO₂ and carbon chemistry, changing instead how the conductive agent is distributed before the slurry is ever mixed. Twenty years later, that same principle - dry-powder premixing under inert gas - underpins the dry electrode processing equipment TOB NEW ENERGY builds today. Ⅰ.
