Battery cell, battery device, and electric device

Abstract

The application discloses a battery monomer, a battery device and an electric equipment. The battery monomer comprises an electrode assembly, a shell and a support. The electrode assembly comprises a main body. The shell comprises a side wall and a bottom wall, and the side wall and the bottom wall jointly enclose a containing cavity, the electrode assembly is located in the containing cavity, and the side wall comprises a first side wall. The support comprises a plate body and a partition, the plate body is connected with the partition, the plate body is located between the bottom wall and the electrode assembly, and the partition extends along the thickness direction of the bottom wall. The partition is located between the electrode assembly and the first side wall, and the partition, the first side wall and the electrode assembly jointly define a flow channel; and / or the electrode assembly comprises at least one pair of partitions, the partition is located between the same pair of electrode assemblies, and the partition and the same pair of electrode assemblies jointly define a flow channel. In the liquid injection process, the electrolyte can be quickly diffused in the electrode assembly along the flow channel after being injected, so that the diffusion speed of the electrolyte is accelerated, and the infiltration rate is improved.
