Wound/Folded Electrode Electrodes TRIZ Cases
- Battery Case Charging Structure to Prevent LiAl Alloy Formation
A high-resistance charging member between the cap plate and terminal prevents case alloying, limits short-circuit current, and improves sealing.
- Battery Cell Heat Conduction Structure for Fast-Charging Thermal Control
A heat conduction structure links the electrode assembly to the case wall, speeding heat removal during fast charging and improving battery reliability.
- Battery Cell Terminal Post Hole for Compact Tab Connection
An inclined terminal-post hole nests the tab inside the connection point, cutting tab space and weight while maintaining stable battery-cell connection.
- Battery Cell Current Collector Layout for Higher Current and Lower Heat
Multiple current collector connection portions raise current capacity at the jelly roll interface and limit heat buildup in the cell.
