CHEMICALLY AND COMPOSITIONALLY MODIFIED SOLID SOLUTION DISORDERED MULTIPHASE NICKEL HYDROXIDE POSITIVE ELECTRODE FOR ALKALINE RECHARGEABLE ELECTROCHEMICAL CELLS |
摘要 |
A high capacity, long cycle life positive electrode for use in an alkaline rechargeable electrochemical comprising: a solid solution nickel hydroxide material having a multiphase structure that comprises at least one polycrystalline .gamma.-phase including a polycrystalline .gamma.phase unit cell comprising spacedly disposed plates with at least one chemical modifier incorporated around the plates, the plates having a range of stable intersheet distances corresponding to a 2+ oxidation state and a 3.5+, or greater, oxidation state; and at least one compositional modifier incorporated into the solid solution nickel hydroxide material to promote the multiphase structure. |
