Berger, M; Demaire, G; Lys, J

Batteries, accumulators or electrochemical generators of electric energy, the negative electrode (Anode) of which consists of at least one alkaline halide, in aqueous or alkaline solution, or of one metallic halide, and one auxiliary electrode collecting current. The positive electrode (Cathode) consists of at least one metallic hydroxide or oxide which can be in solution in the electrolyte and which, preactivated or regenerated continuously by the presence of air or oxygen introduced into the alkaline solution bathing the cathode, supplies the hydroxyl ions necessary for the oxidation of the halide constituting the anode. Furthermore, some compounds of the anode, according to the invention, can be thermally or photonically regenerated. Various applications of these devices, in particular sea water, can be implemented for the supply of electric energy, using easily available and cheap fuel.
