Beschreibung
Zusammenfassung:	An end cover assembly applied to a battery cell includes an end cover provided with an electrode lead-out hole and including a first mating portion provided at a side, facing inside of the battery cell, of the end cover, an electrode terminal disposed at the end cover and covering the electrode lead-out hole, and a connecting member configured to electrically connect the electrode terminal and an electrode assembly of the battery cell. The connecting member includes a second mating portion configured to be mated with the first mating portion to provide deformation resistance of the connecting member along a radial direction of the electrode lead-out hole.
