ABSTRACT:
Hydrides of lithiated nickel dioxide are disclosed, prepared by providing a substantially homogeneous dry intermediate mixture of a starting material containing a nickel compound selected from nickel oxide, nickel hydroxide and mixtures thereof, and optionally including one or more oxides or hydroxides of a transition metal selected from cobalt, iron, chromium, titanium, manganese and vanadium, together with about a 25% stoichiometric excess of lithium hydroxide. The mixture is heat-treated at a temperature above about 600.degree. C. in an atmosphere having a partial pressure of water vapor greater than about two torr. Electrochemical cells are also disclosed, incorporating the disclosed hydrides as a cathode-active material.
