Corrosion

Corrosion management protects battery components — current collectors, terminals, enclosures, and busbars — from electrochemical degradation that shortens cell life and compromises safety. As a hard skill it requires understanding galvanic compatibility between aluminum, copper, and steel, specifying protective coatings, and selecting electrolyte-compatible materials. Engineers apply corrosion knowledge during pack design, supplier qualification, and field-failure analysis where moisture ingress or electrolyte leaks have started attacking metal interfaces.
