<p>A lead storage battery having a prolonged life while causing as little self-discharging and as little reduction of the electrolyte as one comprising a Pb-Ca alloy current collector. A positive plate current collector for lead storage batteries including a surface layer of an alloy composition different from that of the base in at least part of the surface of the base is characterized in that the base is made of a lead alloy not containing Sb or of lead, and the surface layer is a lead alloy layer containing one or more metals selected from alkaline metals and alkaline earth metals.</p> |
