DEVICE FOR SEALING LITHIUM SECONDARY BATTERY ELECTROLYTE INJECTING HOLE

摘要

A polar plate set (22) comprising an anode plate, a cathode plate, and a separator is inserted and installed inside a battery can (1) and a cap assembly (24) having an electrolyte injecting hole (24d) is mounted on an open part of the can so that the can interior is sealed. Furthermore, a rivet-like shaped sealing member (26) is affixed by being inserted in the electrolyte injecting hole (24d) and comes in contact with the cap assembly at an area surrounding the electrolyte injecting hole (24d).
