An end cover assembly includes an end cover, an electrode terminal, and a sealing member. The end cover is provided with a lead-out hole. The electrode terminal at least partially passes through the lead-out hole, and a sealing gap is formed between them. The electrode terminal has a combination interface, and the combination interface is connected to the sealing gap at a junctional position. The sealing member is arranged in the sealing gap to seal the electrode terminal and the end cover. In a direction from the inside of the first housing to the outside of the first housing along the sealing gap, the sealing member comprises a sealing starting section located upstream of the junctional position, where the length of the sealing starting section is d, and the thickness of the sealing starting section is t, with d>t.
