AI Technical Summary

Technical Problem

Existing storage cells with fuse portions face the challenge of recombination after the fuse is blown due to vibrations or other external factors.

Method used

The energy storage cell design includes a current path with a fuse section that is subjected to tensile stress in a direction that separates the fuse ends, preventing recombination by applying stress to pull the fused ends apart.

Benefits of technology

The design effectively prevents the recombination of blown fuse portions, ensuring a stable and reliable current path even after the fuse is activated.

Abstract

To provide a fuse part which is not easily re-coupled.SOLUTION: A power storage cell includes a cell case and an electrode body. The cell case houses the electrode body. The cell case includes an electrode terminal. A current path is formed in the cell case. The current path electrically connects the electrode body with the electrode terminal. The current path includes a fuse part. Tensile stress is applied to the fuse part in a direction in which the fuse part is separated.SELECTED DRAWING: Figure 4
