Title:

ENERGY STORAGE DEVICE AND STATE DETECTION METHOD FOR ENERGY STORAGE DEVICE

Document Type and Number:

WIPO Patent Application WO/2024/019130

Kind Code:

A1

Abstract:

This energy storage device comprises: an energy storage element; a bottomed, cylindrical case that accommodates the energy storage element and has an opening at one end; a sealing member that seals the opening; and a current collector plate 14. The current collector plate 14 comprises: a first region 14A that is electrically connected to an external terminal of the sealing member or the case; second regions 14B that are joined to the electricity storage element; one or a plurality of first conductive sections 15A that link the first region and the second regions; and one or a plurality of second conductive sections 15B that link the first region and the second regions. The electrical resistance of the first conductive sections 15A and the electrical resistance of the second conductive sections 15B are different.
