A rechargeable metal hydride alkaline battery is provided, wherein the paste comprises an active cathode composition applied to a conductive substrate, and is manufactured by a method comprising exposing a paste electrode to a high temperature for a desired period of time. Using a positive electrode that results in improved cycle life, lower internal resistance and improved energy utilization. The positive electrode composition includes a particulate positive electrode active material, a polymer binder, and optionally one or more additives. The positive electrode active material is, for example, nickel hydroxide or modified nickel hydroxide. In the case of a nickel foam substrate, the positive electrode composition may not contain a binder. |
