Novel additives are disclosed comprising a material capable of absorbing hydrogen and recombining oxygen, which additive is ideally suited for incorporation in sealed cells. The additive may be disposed in an energy storage device in several manners such as a coating on a negative electrode, a thin layer disposed between cell separators, an auxilliary electrode, and as one negative electrode in a device having a plurality of negative and positive electrodes.
