Abstract
Corrosion is prevented in a non-aqueous cell, having iron containing components kept at cathode potentials above 2.5 volts, by the inclusion within said cell of an additive comprised of a lewis base tertiary amine particularly heterocyclic imides such as 1,3-dimethylimidazolidinone and 3,5 dimethylisoxazole wherein all the nitrogens thereof contain no acidic protons.
