backup current source

Thin-layered magnesium anodes on steel base were made by magnetron spraying. Physical-mechanical properties of this anodes in neutral liquid ammonia electrolyte were determined. The results obtained show that magnesium coating with disordered porous structure provide least time of activation, high discharge currents and can be used as anodic layer of bipolar electrodes of reserve current sources.

Modern technology causes the renewal of the interest to physical and chemical properties of solid oxide electrodes. Among these, PbO₂/substrate has attracted considerable attention due to its application as an electrode in backup current sources. It was shown that the stable and active lead dioxide coating can be produced by appropriate pretreatment of the titanium substrate, including the coating of the substrate with colloidal graphite.
