A process for producing a nickel compound containing lithium comprising the step of:
- allowing (1) metallic lithium and (2) nickel oxyhydroxide and/or a nickel oxyhydroxide having some of its constituent elements substituted by at least one element selected from cobalt, zinc and lithium to undergo reaction in an organic solvent.
A process for producing a nickel compound containing lithium comprising the step of:
- allowing (1) a lithium compound capable of reducing nickel oxyhydroxide and/or a nickel oxyhydroxide having some of its constituent elements substituted by at least one element selected from cobalt, zinc and lithium and (2) nickel oxyhydroxide and/or a nickel oxyhydroxide having some of its constituent elements substituted by at least one element selected from the group consisting of cobalt, zinc and lithium to undergo reaction in an organic solvent.
A process for producing a nickel compound containing lithium, whose nickel valence is lower than three, comprising the step of:
- allowing (1) a lithium compound, (2) a substance capable of reducing nickel oxyhydroxide and/or a nickel oxyhydroxide having some of its constituent elements substituted by at least one element selected from cobalt, zinc and lithium and (3) nickel oxyhydroxide and/or a nickel oxyhydroxide having some of its constituent elements substituted by at least one element selected from cobalt, zinc and lithium to undergo reaction in an organic solvent.
A nonaqueous electrolytic battery comprising a nickel compound containing lithium as an active positive electrode material, wherein the nickel compound containing lithium is obtained by a process comprising the step of:
- allowing (1) metallic lithium and (2) nickel oxyhydroxide and/or a nickel oxyhydroxide having some of its constituent elements substituted by at least one element selected from cobalt, zinc and lithium to undergo reaction in an organic solvent.
