Abstract
The invention is a lithium secondary battery that prevents electrolyte and internal gas leakage by durably sealing the electrolyte injecting hole. The lithium secondary battery consists of a battery can, which contains a polar plate set with an anode plate, and a separator inserted and installed inside the battery can. The opening of the battery can has a cap assembly with an electrolyte injecting hole so that the can interior can be sealed. To seal the battery can, a rivet shaped sealing member is inserted in the electrolyte injecting hole. The sealing member is placed in contact with the cap assembly at an area surrounding the electrolyte injecting hole and affixed to the cap assembly.
