A lead accumulator having an electrolyte and a grid substrate. The grid substrate is formed of an alloy of lead with a metal, or a mixture of metals, selected from, first antimony, which alloy further contains any one of the metals sodium, lithium, potassium or tin. Secondly calcium, and further containing tin, tin and antimony or tin and aluminum. Thirdly calcium with no antimony and a coating of tin or an alloy of lead and tin. The electrolyte in the first and second cases contains alkaline earth metal ions. In the third case, the electrolyte contains alkaline earth and alkali metal ions. The accumulator improves the performance and properties of conventional lead accumulators and is resistant to the deleterious effects of being allowed to stand in a discharged condition. |
