High discharge rate electrodeposited zinc electrode for use in alkaline microbattery

High discharge rate zinc electrode is prepared using the electrodeposition process. The electrolytic bath consists of zinc chloride as the metal source and ammonium chloride as the supporting electrolyte. The concentration of the supporting electrolyte is varied from zero until 4 M, while the concen...
