Abstract

Secondary batteries with aqueous acid solutions of lead salts as electrolytes and inert electrode base plates also contain redox systems in solution. These systems have a standard potential of from -0.1 to +1.4 V relative to a standard hydrogen reference electrode, do not form insoluble compounds with the electrolytes and are not oxidized or reduced irreversibly by the active compositions applied to the electrode base plates, within their range of operating potentials.
