Battery Tab-to-Terminal Joint Using Conductive Adhesive Buffer

A conductive member is introduced as an intermediary element between the electrode tab and the electrode terminal. This conductive member serves as a mediator that distributes stress across a larger area, preventing stress concentration at the connection point while maintaining electrical conductivity. The conductive member acts as a buffer zone that absorbs mechanical stress during vibration or dropping events, thereby improving connection reliability without significantly complicating the overall structure.

The conductive member is designed with localized functionality, concentrating the stress-distribution function in a specific region between the electrode tab and terminal. By placing the conductive member only at the critical connection interface rather than expanding the entire connection area, the solution achieves improved adhesive strength through localized stress management while preserving the compactness of the overall battery structure. The conductive member's small form factor allows it to fulfill its stress-distribution function without significantly increasing the battery volume.
