About lithium battery steel case?

As a key component of the battery system, the battery case plays a role in fixing and fully sealing the internal electrochemical system.

Steel battery pack shells are generally welded by cast steel plates. High strength, high rigidity, heavy weight, the surface needs anti-corrosion treatment, so that it still has a good anti-corrosion effect under long-term high temperature conditions.

Cylindrical lithium batteries mostly use steel materials with strong physical stability as the shell material.

In order to prevent the oxidation of the positive active material of the battery to the steel shell, manufacturers usually use nickel plating to protect the iron matrix of the steel shell.

Cylindrical lithium-ion battery case uses battery-specific BDcK cold-rolled material, battery steel.
