Abstract

A battery cell (20), a battery (100), and an electric apparatus are provided, belonging to the field of battery technology. The battery cell (20) includes a housing (21) and an end cover (22). An accommodating cavity (211) is formed inside the housing (21). At least one end of the accommodating cavity (211) in a first direction (X) is provided with an opening (212). The accommodating cavity (211) is configured to accommodate an electrode assembly (23). The end cover (22) includes a first cover body (221) and a second cover body (222) stacked along the first direction (X). The first cover body (221) is connected to the housing (21) to seal the opening (212). Strength of the second cover body (222) is greater than strength of the first cover body (221). Setting the strength of the second cover body (222) to be greater than the strength of the first cover body (221) allows the end cover (22) of this structure to be provided with the second cover body (222) having higher strength on one side of the first cover body (221), thereby improving the overall structural strength of the end cover (22). Thus, when the end cover (22) has the same structural strength, the end cover (22) can be connected to the housing (21) through the first cover body (221), and the overall thickness of the first cover body (221) and second cover body (222) of the end cover (22) after stacked in the first direction (X) can be optimized.
