Battery monomer and processing method thereof, battery and power utilization device

Abstract

The invention discloses a battery monomer, a processing method thereof, a battery and an electric device, and belongs to the technical field of batteries. The battery monomer comprises a shell part, a pole part and a battery core part, the shell part is provided with an accommodating cavity and comprises a first shell wall participating in limiting the accommodating cavity, the pole part is mounted on the first shell wall and comprises a pole main body, the battery core part comprises at least one battery core group, the battery core group comprises n battery core main bodies, the n battery core main bodies are all arranged in the accommodating cavity, and the n battery core main bodies are arranged in the accommodating cavity. The plurality of battery core main bodies are sequentially arranged along the first direction, the end part of each battery core main body is connected with a tab group, all the tab groups of the battery core group extend towards the middle position of the battery core group in the first direction and are connected to form a tab part, the tab part is electrically connected with the pole main body, and n is greater than or equal to 1 and is a positive integer. Therefore, the reliability of the battery cells can be improved.
