Wound/Folded Electrode Electrodes TRIZ Cases
- Secondary Battery Tab Lead-Out Device for Stable Connection
Tab lead-out device with conductive and insulating layers connects battery tabs to the cover plate.
- Sealed Battery Groove Captures Weld Spatter
Grooves around resistance-welded collectors capture spattered particles, preventing internal short-circuits caused by copper welding debris.
- Secondary Battery Current Collector Plate Local Thickness Design
A secondary battery current collector plate uses varying thickness regions to optimize welding and heat dissipation.
- Spatially Varying Thermal Conductivity Heat Conductor for Battery Cells
A heat conducting member with spatially varying thermal conductivity optimizes waste heat transfer from battery electrodes to fluid channels.
- Wound Electrode Assembly Adhesive Layer Alignment
An adhesive layer with 4-12 N/m force stabilizes stepped electrode sheets, preventing misalignment and corrosion during manufacturing.
- Non-aqueous Battery Solid Electrolyte Gas Generation for Overcharge Protection
Solid electrolyte layer generates gas to activate the electricity shut-off mechanism in non-aqueous batteries.
- Rechargeable Battery Fuse With Sliding Insulation
Sliding insulation separates melted fuse parts via gas pressure, extinguishing arcs and improving short-circuit safety.
