Power Storage Cell - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240258663 titled 'Power Storage Cell

The abstract of the patent application describes a power storage cell comprising a cell case and an electrode assembly. The cell case houses the electrode assembly and includes a top wall, a peripheral wall, and a bottom wall. The top wall faces the bottom wall and is provided with an electrode terminal. A current path that electrically connects the electrode terminal and the electrode assembly is formed in the cell case, including a fuse portion. Additionally, the power storage cell includes at least one of a thermal expansion member and a thermal contraction member, which help support the electrode assembly.

• The power storage cell features a cell case with a top wall, peripheral wall, and bottom wall.
• An electrode terminal is located on the top wall, connecting to the electrode assembly via a current path with a fuse portion.
• The cell includes a thermal expansion member between the top wall and the electrode assembly for support.
• A thermal contraction member is also present between the electrode assembly and the peripheral wall or bottom wall to further support the assembly.

Potential Applications: - Energy storage systems - Electric vehicles - Portable electronic devices

Problems Solved: - Ensures stable and secure housing for the electrode assembly - Helps prevent damage due to thermal expansion and contraction
