Abstract

A rechargeable battery is provided such that the positive electrode comprises lead dioxide, the negative electrode zinc, and the electrolyte is alkaline. Upon discharge, the lead dioxide is reduced to lead oxide, the zinc is oxidized to zinc oxide, and the electrolyte remains unchanged. The reactions are reversed when the battery is charged.

Claims

1. A storage battery comprising:

(a) a positive electrode of lead;

(b) a negative electrode of zinc; and

(c) an alkaline electrolyte.

2. A storage battery of claim 1 in which the alkaline electrolyte is an aqueous solution of a hydroxide of an alkali metal selected from the group lithium, sodium, potassium, and cesium.

3. A storage battery of claim 1 in which the alkaline electrolyte is an aqueous solution of tetramethyl ammonium hydroxide.

4. A storage battery of claim 1 in which the alkaline electrolyte contains a buffering agent selected from the group carbonates, borates, silicates, and phosphates.
