Abstract
Described is a battery cell, which includes a casing having a first opening; an electrode assembly received in the casing, the electrode assembly having a first tab, a second tab and a third tab, the first tab having an opposite polarity to the second tab, and the third tab having the same polarity as the first tab or the second tab; an end cap for closing the first opening; an insulating member disposed between the end cap and the electrode assembly, wherein the third tab is configured to be connected with the insulating member. It is possible to improve the heat dissipation efficiency of the battery cell by additionally providing a heat dissipation path of the electrode assembly—the third tab—the insulating member—the end cap, thereby improving the overcurrent capacity and the safety performance of the battery cell.
