The parts of the electrode assembly corresponding to the coated areas of the first pole piece and the second pole piece are body parts. The non-coated area of the first pole piece or the second pole piece forms the tabs. The separator is used to isolate the first pole piece from the second pole piece. The end cap assembly is used to close the opening. The end cap assembly comprises an end cap and a first insulator. The end cap covers the opening and is connected to the housing. The first insulator is disposed on the side of the end cap close to the inside of the housing. The first insulator has a recess. The tabs are accommodated within the recess. At least a portion of the inner wall of the recess is arranged around the periphery of the tabs.
