CAP ASSEMBLY FOR PREVENTING ELECTRICAL SHORTING AND SECONDARY BATTERY INCLUDING THE SAME

WIPO Patent Application WO/2018/030679

A1

The present invention relates to a cap assembly for preventing electrical shorting in a secondary battery and a secondary battery including the cap assembly. The cap assembly includes a cap-up attached with an elastic plate adapted to interrupt the flow of electric current by internal heat of the secondary battery, a CID module interrupting the flow of electric current by internal pressure of the secondary battery, and an insulating member interposed between the cap-up and the CID module. The cap assembly prevents the occurrence of electrical shorting in a secondary battery when a gasket between a battery can and the cap assembly and/or an insulating layer between a safety vent and a cap-down is dissolved or lost upon abnormal operation of the secondary battery so that the battery can is brought into close contact with the cap assembly and/or the safety vent is brought into close contact with the cap-down.
