SECONDARY BATTERY AND METHOD FOR PRODUCING SECONDARY BATTERY

摘要

Disclosed is a secondary battery capable of preventing damage to a current interrupt device caused by generation and transmission of vibration, and thereby achieving prevention of malfunction of the current interrupt device, and improvement of quality of the secondary battery. In addition, disclosed is a method of manufacturing the secondary battery. Specifically disclosed is a secondary battery, in which a positive electrode terminal is placed on the upper face of a sealing plate, a holder is placed on the lower face of the sealing plate, and the sealing plate is joined to the positive electrode terminal and the holder by a rivet. The secondary battery includes an adhered portion for adhering the holder to the sealing plate.

主权项

1. A secondary battery comprising:
a rivet; a collector tab; a current interrupt device which includes a reverse plate acting as a diaphragm and connected to the rivet, and a holder as an insulator for holding the collector tab, and which is formed by welding the reverse plate to the collector tab at a predetermined welding strength; a positive electrode terminal; a sealing plate which is joined to the positive electrode terminal and the holder by the rivet, the positive electrode terminal being placed on an upper face of the sealing plate, the holder being placed on a lower face of the sealing plate; and an adhered portion for adhering the holder to the sealing plate.
