Zusammenfassung:	The embodiments of the present application relate to the field of batteries. Provided are an end cover assembly, a battery cell, a battery and a device, which is configured to improve the performance of the battery cell. The end cover assembly comprises a cover plate, a first insulating member, an electrode terminal, an adsorbing member and a sealing member. The cover plate is provided with a mounting through hole, and the mounting through hole penetrates the cover plate in an axial direction of the mounting through hole; a flow guide channel is arranged between the first insulating member and the cover plate; the flow guide channel is in fluid communication with the mounting through hole; the electrode terminal is mounted in the mounting through hole; the adsorbing member is placed in the flow guide channel; and the sealing member is configured to seal the mounting through hole. According to the technical solution, an electrolyte entering along a gap between the cover plate and the first insulating member in
