Abstract

A rechargeable battery is provided such that the positive electrode comprises lead dioxide, the negative electrode comprises a metal selected from the group consisting of iron, zinc, cadmium, lanthanum/nickel alloys and titanium/zirconium alloys, and the electrolyte is an aqueous alkali-metal acetate. Upon discharge, the lead dioxide is reduced to lead oxide, and the electrolyte remains unchanged. The reactions are reversed when the battery is charged.

Claims

exact text as granted — not AI-modified
1 . A storage battery comprising:
 a. a positive electrode which exists as lead dioxide in the charged condition,   b. a negative electrode of metal, and   c. an aqueous electrolyte comprising an alkali metal acetate.   
     
     
         2 . A storage battery of  claim 1  in which the metal is selected from the group consisting of iron, zinc, cadmium, lanthanum/nickel, and titanium/zirconium alloy. 
     
     
         3 . A storage battery of  claim 1  in which the alkali metal is selected from the group lithium, sodium, potassium, rubidium, and cesium.
