Abstract
There is provided a sealed secondary battery whose current-blocking system yields little change in the actuation pressure even on long-term use. The sealed secondary battery comprises a current-blocking systemthat is actuated by a pressure rise inside a battery caseto disconnect conduction path between an electrode and an electrode terminal. Current-blocking systemcomprises a pressure-sensitive member having a pressure-sensitive deformable portionthat deforms from a first state via snap-through deformation to a second state upon a pressure rise inside battery case, and is configured to disconnect the conduction path by snap-through deformation of pressure-sensitive deformable portion
