TOP COVER ASSEMBLY, MANUFACTURING METHOD FOR SAME, TOP COVER MANUFACTURING METHOD, AND BATTERY CELL

A top cover assembly (1) for a battery cell comprises: a top cover (11) having an electrode lead-out hole (111) and an electrode terminal (151, 152) fastened to the top cover (11) by a fastener, the the electrode terminal (151, 152) being located at one side of the top cover (11) and covering the electrode lead-out hole (111), and a sealing member (12) being disposed between the electrode terminal (151, 152) and the top cover (11) to seal the electrode lead-out hole (111). One of the sealing member (12) or the top cover (11) is provided with a protrusion, and the other is provided with a recess receiving the protrusion. The protrusion and the recess engage, thereby limiting displacement of the sealing member (12). The invention prevents the sealing member (12) from moving during use by the engagement between the protrusion and the recess of the sealing member (12) and the top cover (11), thereby ensuring sealing of the battery cell, and increasing the service life thereof.
