LEAD STORAGE BATTERY WITH EXPANDER SUPPLY ABSTRACT OF THE DISCLOSURE The electrodes are supplied with expander material by providing a storage container with corrodible walls located in the acid electrolyte, which liberates its contents only after the original expander content of the negative active mass has already been significantly depleted. The wall material is either a plastic having limited acid resistance, or one of the metals Pb, Sb, Sn, or an alloy thereof. When using Sb, there exists a combined supply of expander and antimony. The latter counteracts the tendency toward crumbling of the positive mass which exists in Sb-free plates.
