Abstract

The present invention relates to a cap assembly to be mounted on the open upper end of a cylindrical container in a battery structure in which an electrode assembly (gel roll) of an anode / separator / cathode structure is covered Built in a cylindrical container. The cap assembly includes: a scored safety vent secured so that the safety vent can be ruptured by high pressure gas from the battery; a protruding upper end cap attached along the outer surface of the safety vent; mounted on the upper end cap a liner on an outer surface of the battery; and a fire extinguishing member comprising a fire extinguishing component for preventing fire of the battery, at least a portion of which is mounted at an interface between the upper end cap and the liner.

Description

technical field [0001] The present invention relates to a cap assembly having a novel structure, and more particularly, to a cap assembly arranged at an open upper end of a cylindrical container of a battery configured to have a structure in which a cathode The electrode assembly (gel roll) of / separator / anode structure is installed in a cylindrical container, the cap assembly includes: a safety vent with predetermined cuts, the cuts are configured to be exposed to the high voltage in the battery a gas rupture; a protruding top cap connected to a safety vent along its periphery; a gasket mounted at the periphery of the top cap; and a fire extinguishing member containing a fire extinguishing component to prevent the battery from igniting, At least a portion of the fire suppression member is mounted at the interface between the overcap and the liner. Background technique [0002] As mobile devices have been increasingly developed and the demand for such mobile devices has inc...
