Abstract

A battery cell (10), a battery (100), an electrical device, and an energy storage apparatus. The battery cell (10) comprises a housing (1), a separation apparatus (7) and multiple electrode assemblies (2). The housing (1) is provided with an accommodating space (13), the multiple electrode assemblies (2) being accommodated in the accommodating space (13), and the separation apparatus (7) being disposed in the accommodating space (13), the separation apparatus (7) is configured to divide the accommodating space (13) into multiple sub-spaces (131), each sub-spaces (131) accommodating at least one electrode assembly (2). The separation apparatus (7) provides a separation function for the electrode assemblies (2) in each sub-space (131), so as to reduce the accumulation of expansion stress of electrode assemblies (2) in adjacent sub-spaces (131), thereby reducing the risk of the electrode assemblies (2) compressing and deforming each other, and effectively improving the reliability of a battery cell (10).
