As a key component of the battery system, the battery housing plays a role in fixing and fully sealing the internal electrochemical system. The structural strength and heat dissipation performance of the shell are important indicators for measuring the battery's working ability. Cylindrical lithium batteries often use steel materials with strong physical stability as the shell material. In order to prevent oxidation of the steel shell by the positive electrode active material of the battery, nickel plating is usually used to protect the iron matrix of the steel shell.
