SEALED BATTERY
First Claim
1. A sealed battery, comprising:
- an electrode assembly;
an outer case housing the electrode assembly;
a sealing lid for closing an opening of the outer case; and
a current cutoff valve that is deformed by abnormal internal pressure in the outer case, whereina plurality of conductive members for carrying current between the current cutoff valve and electrode assembly are attached to the current cutoff valve, andthe plurality of conductive members are configured so as to be broken off in a stepwise manner by the deformation of the current cutoff valve as a result of abnormal internal pressure, thereby shutting off the current flowing between the current cutoff valve and electrode assembly.

Abstract
A sealed battery (100) provided in the present invention includes an electrode assembly (80), an outer case (40) housing the electrode assembly (80), a sealing lid (20) for closing an opening (42) of the outer case (40), and a current cutoff valve (22) that is deformed by abnormal internal pressure in the outer case (40). A plurality of conductive members (10) for carrying current between the current cutoff valve (22) and electrode assembly (80) are attached to the current cutoff valve (22). The plurality of conductive members (10) are configured so as to be broken off in a stepwise manner by the deformation of the current cutoff valve (22) as a result of abnormal internal pressure, thereby shutting off current flowing between the current cutoff valve (22) and electrode assembly (80).
