Title:
NONAQUEOUS-ELECTROLYTE SECONDARY CELL
Document Type and Number:
WIPO Patent Application WO/2019/216267
Kind Code:
A1
Abstract:
A nonaqueous-electrolyte secondary cell is provided with which it is possible to cause a powering interruption mechanism to operate reliably during overcharging without reducing cell performance. The nonaqueous-electrolyte secondary cell 1 comprises: a positive electrode 41 inside a container 2; in-container positive electrode terminals 21, 23; a negative electrode 42; in-container negative electrode terminals 22, 24; a nonaqueous electrolytic solution; and a powering interruption mechanism 68b that can interrupt powering with a unit outside the container when the container internal pressure has increased. A positive-electrode mixture layer non-formed section 41b, or at least one of the in-container positive electrode terminals 21, 23, comprises a positive-electrode active material layer that generates a gas that enables operation of the powering interruption mechanism 68b.
