Secondary Cells Servicing/Maintenance TRIZ Cases
- Lithium-ion Battery Sulfur Additive Gas Suppression
Sulfur additive deposits protective film on vanadium phosphate positive electrode to suppress gas generation and maintain shape stability.
- Modular Battery Pack with Heat Pipe Cooling
Segmented modules share cooling devices via heat pipes, reducing architecture complexity while maintaining uniform temperature distribution.
- Lithium Battery Electrolyte Additive for SEI Film Formation
Specific additive compounds suppress electrolyte decomposition and form protective solid electrolyte interface films to enhance cycle-life characteristics.
- Fluorinated Acrylate Electrolyte for Rechargeable Lithium Battery
Fluorinated acrylate additives resolve the contradiction between flame retardancy and cycle life by reducing interface resistance.
- Alpha-Alumina Porous Membrane Slurry Redispersibility
Alpha-alumina modified particles stabilize slurry homogeneity through surface treatment.
- Solid Polymer Wax Coated Separator for Lithium-Ion Battery Safety
A lithium-ion battery separator applies a solid polymer wax coating that melts at 85–120°C to capillary-enter micropores and prevent short circuits.
- Fluorinated Alkylbenzoate Additives for High-Voltage Battery Overcharge Protection
Alkylbenzoate derivatives oxidatively polymerize at the cathode to form protective films during overcharge events.
