Properties of Alternate Electrolytes for Secondary Zinc Batteries

Abstract

Several mixed aqueous electrolytes have been characterized for zinc oxide solubility, ionic conductivity, density, and nickel hydroxide utilization. These electrolytes were made by reducing the usual potassium hydroxide concentration and by adding the salts such as potassium fluoride or potassium phosphate to partially compensate for the lower ionic conductivity. These mixed electrolytes may be useful in prolonging the cycle life of the zinc electrode in secondary batteries.
