Document Type and Number:
WIPO Patent Application WO/2024/026829
Kind Code:
A1
Abstract:
A battery cell (20), a battery (100), and an electrical apparatus. The battery cell (20) comprises: a housing (21) having an opening (211); and an end cover assembly (23) used for closing the opening (211), the end cover assembly (23) comprising an electrode terminal (232). An electrode assembly (22), an adapter (24), and an insulating member (25) are further provided in the housing (21). The electrode assembly (22) comprises tabs (221), the adapter (24) is used for electrically connecting the tabs (221) and the electrode terminal (232), and the insulating member (25) is used for insulating the adapter (24) from the housing (21). The provided battery cell (20), battery (100) and electrical apparatus can alleviate the problem of thermal failure of the battery cell (20) caused by thermal diffusion in the use process of the battery cell (20), thereby improving the safety performance of the battery cell (20) and the battery (100) using same.
