New Energy Battery Shell Materials

The pre nickel plating process can accurately control the thickness and uniformity of the single-sided coating according to customer needs, in order to improve the consistency of the stamped battery case.

The thickness of the inner and outer coating of the pre nickel plated steel strip is uniform and undergoes alloying treatment, thereby improving the rust prevention ability of the steel shell; The nickel plated steel shell has uneven coating and poor rust prevention ability.

Pre plated nickel steel strip forms a nickel iron alloy layer during continuous annealing, increasing the adhesion of the coating; Simultaneously increasing the ductility of the nickel layer, stamping does not produce cracks.

By using deep drawing grade battery steel base tape combined with advanced continuous annealing and electrical discharge texturing technology, a good alloy diffusion layer and surface roughness are formed, increasing lubrication and uniform stretching.
