AI Technical Summary
Technical Problem
In the preparation of battery cells, the prior art is difficult to reduce the production difficulty and cost, especially in terms of sealing and humidity control of liquid injection holes.
Method used
A battery cell is designed, including an outer casing and a switch valve. The switch valve is composed of a base, a seal and a snap-on part. The electrolyte is injected into the shell through the second through hole on the base, and the second through hole is sealed after the injection is completed, reducing the requirements for subsequent preparation of ambient humidity.
Benefits of technology
This technical solution reduces the difficulty and cost of preparing battery cells, simplifies the preparation process, and improves the sealing and service life of battery cells.

Abstract
The embodiment of the utility model provides a battery monomer, a battery and electric equipment, the battery monomer comprises a shell and a switch valve, and the wall part of the shell is provided with a first through hole; the switch valve comprises a base and a sealing piece, the base is installed in the first through hole, the base is provided with a second through hole communicating with the inner space of the shell, the sealing piece is arranged on the outer side of the wall part and connected to the base, and the sealing piece is configured to move relative to the base so as to block or open the second through hole. By arranging the second through hole in the shell, when the second through hole is opened, electrolyte can be injected into the shell, and after the electrolyte is injected, the second through hole can be blocked, so that the requirement on the humidity of a preparation environment of the battery monomer is relatively low when the battery monomer is subsequently prepared, and the preparation difficulty and cost of the battery monomer can be reduced; and the switch valve can be used as a part of a battery monomer finished product and does not need to be taken down after the battery monomer is prepared, so that the preparation of the battery monomer is simpler.
