An improved rechargeable nickel-zinc battery is described which is capable of undergoing many charge-discharge cycles (cycle life), with deep discharge, and of high performance with heavy drain discharge during use. The increased cycle life is accomplished by a suitable combination of electrochemical generating elements. The high performance with heavy drain discharge service is obtained by an improved zinc electrode construction. The battery of this invention has a sheet-like kneaded zinc electrode, a sheet-like nickel oxide electrode with limited capacity ratio thereof, a separator, an electrolyte absorber, and a concentrated alkaline electrolyte in limited amounts.
