BATTERY CELL, BATTERY, ELECTRICAL EQUIPMENT AND PREPARATION METHOD FOR BATTERY CELL

A battery cell, a battery, an electric device, and a method for preparing a battery cell are described. The battery cell includes: a housing having an opening; an end cap assembly for closing the opening; an electrode assembly accommodated inside the housing; and a receiving component accommodated inside the housing, the receiving component being used for accommodating the electrode assembly and an electrolyte. In the technical solution of the present application, the receiving component is arranged inside the housing, and the electrolyte and the electrode assembly are both stored in the receiving component, so that the receiving component can isolate the electrolyte from the housing and the end cap assembly to a certain extent, and the receiving component plays a certain role in secondary sealing of the electrolyte.
