Rechargeable Battery Side Retainer Arc Debris Exhaust Guide

The harmful arc debris is extracted from the general battery interior space and directed into a specific containment region. The side retainer with exhaust guide member separates the arc debris generation zone from the electrode assembly and case, allowing the fuse to maintain its protective function while isolating its harmful byproduct (arc debris) into a designated area between the side retainer and case.

The side retainer acts as an intermediary structure between the fuse and the electrode assembly/case. It introduces a new component that mediates the interaction by providing a physical barrier and guidance path, preventing direct contact between arc debris and sensitive components while maintaining the fuse's current-interrupting function.

The harmful arc debris is converted from a damaging factor into a contained element. Instead of allowing arc debris to randomly scatter and damage components, the exhaust guide member channels it into a specific region between the side retainer and case, where it cannot cause harm. The harmful kinetic energy of arc debris is redirected into a controlled path that benefits overall system safety.

The problem is solved by introducing a spatial dimension consideration. Rather than relying solely on the horizontal placement of components, the invention utilizes the vertical dimension by positioning the side retainer and exhaust guide member to create a three-dimensional containment space. Arc debris is directed into this vertical space between the side retainer and case, preventing lateral penetration into the electrode assembly.
