With the development of electrochemical energy storage technology, the energy density is higher and higher. In particular, for lithium ion batteries, very high energy densities can be achieved. Under the working state, ions in the lithium ion battery move at a high speed and generate electrochemical reaction, so that the internal temperature of the lithium ion battery is increased, and if heat cannot be discharged in time, the risk of thermal runaway exists. Therefore, for energy storage cells such as lithium ion batteries, it is extremely important to control temperature and heat. Most of the existing battery monomers adopt square or round solid structures, and although the volume energy density can be increased, the heat inside the battery monomers is difficult to discharge, so that the safety risk exists.
In view of this, in order to improve the heat dissipation performance of the battery cell, a ring-shaped battery has been proposed. Compared with a solid cylindrical battery, the annular battery can increase the heat dissipation area through the hollow channel in the inner shell, so that heat generated in the battery can be discharged more quickly, and the safety performance is improved. However, in order to realize stable charge and discharge, the conventional ring battery needs to have a complicated connection structure and an insulating structure at both ends, which results in complicated structure and difficult processing.
