Battery monomer, battery and electric equipment

The embodiment of the invention provides a battery monomer, a battery and electric equipment, and belongs to the technical field of batteries. The battery monomer comprises a shell, an electrode terminal, an electrode assembly, an insulating part and a liquid absorbing component, the shell comprises a first wall; the electrode terminal is arranged on the first wall; the electrode assembly comprises a main body and a tab extending from the main body, and the tab is electrically connected with the electrode terminal; the insulating part is arranged between the first wall and the electrode assembly and is used for isolating the first wall from the electrode assembly; and the liquid absorption component is positioned between the main body and the insulating part and is used for absorbing the electrolyte. The battery monomer has relatively high reliability.
