AN IMPROVED BATTERY MOUTH-SEALING ASSEMBLY AND A BATTERY INCLUDING THE SAME

摘要

A battery enveloping assembly and a battery incorporating such an enveloping assembly are disclosed. The enveloping assembly comprises an explosion-proof assembly and an enveloping plate. A casing extends downwardly from the enveloping plate. An external surface of the enveloping plate is provided with a connection portion protruding outwardly relative to the casing. A cavity configured to house the explosion-proof assembly is formed in the casing. A lower portion of the casing is bent inwardly to form a bending portion so as to secure the explosion-proof assembly inside the casing in an insulating and sealing manner. A first through hole through which an electrode is connected to the explosion-proof assembly is provided at a center of the bending portion, and a second through hole through which an electrode extends out from the explosion-proof assembly is provided in the enveloping plate which is disposed on the top of the casing.
