Abstract
A heavy metal-free rechargeable Zinc electrode for use in storage cells having alkaline electrolyte has been developed. The electrode includes a current collector and an active mass based on metallic zinc and zinc oxide powders, calcium hydroxide, indium hydroxide, indium sulfate, bismuth-oxide and a binder. The electrodes have been successfully used in Ni—Zn and Ag—Zn cells. The electrodes lead to environmentally benign alkaline cells. The electrodes have additional advantages over the prior art electrodes in terms of initial capacity and cyclability.
