ABSTRACT:
A high capacity long cycle life positive electrode which includes an electronically conductive substrate for conducting electricity through the electrode and an electrochemically active nickel hydroxide material in electrical contact with the electronically conductive substrate, the electrochemically active nickel hydroxide material is composed of at least two different solid solution nickel hydroxide materials each having differing compositions. The positioning of the at least two different solid solution nickel hydroxide materials and their relative compositions alter the local redox potential or porosity to force discharge of the electrode in a stepwise fashion from the nickel hydroxide material remote from said conductive network or substrate, through any intermediate nickel hydroxide materials, to the nickel hydroxide material adjacent the conductive network or substrate.
