Power Storage Cell

Abstract

A power storage cell includes a cell case and an electrode assembly. The cell case houses the electrode assembly. The cell case includes a top wall, a peripheral wall, and a bottom wall. The top wall faces the bottom wall. The peripheral wall connects the top wall and the bottom wall. The top wall 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. The current path includes a fuse portion. The power storage cell further includes at least one of a thermal expansion member and a thermal contraction member. The thermal expansion member is disposed between the top wall and the electrode assembly. The thermal contraction member is disposed between the electrode assembly and at least one of the peripheral wall and the bottom wall. The thermal contraction member supports the electrode assembly.
