Abstract
An end cover assembly may include: a cover plate provided with an electrode lead-out hole; an electrode terminal located on one side of the cover plate in a thickness direction and covering the electrode lead-out hole; and a sealing element disposed between the electrode terminal and the cover plate so as to seal the electrode lead-out hole along a circumference of the electrode lead-out hole. The sealing element may include a body and a first insulating element. The first insulating element may be connected to the body and have a higher melting point than the body. The first insulating element may be configured to insulate the electrode terminal from the cover plate after the body is melted, so as to keep electrode terminals of two polarities insulated from each other at thermal runaway of a battery cell.
