Generally speaking, the power battery steel shell is made of stainless steel and carbon steel, and the steel may rust after being used for a long time. Therefore, it is particularly important to prevent rust or deal with rust stains.
Before anti-rust treatment, first clean the residual electrolyte on the surface of the battery with clean water. Then immerse the cleaned battery in the passivation diluent for 1 minute. After a passivation protective film is formed on the surface of the battery's steel case, take the battery out and clean it with clean water again, immerse the battery in alcohol for cleaning and dry it.
This anti-rust treatment method can obviously improve the anti-rust effect of the battery steel shell by carrying out a large-scale anti-rust treatment on the steel shell of the battery, prolong its service life and improve the production efficiency of the battery.
