PROBLEM TO BE SOLVED: To produce lithium-nickel oxide particulate powder capable of firing in a short time, uniform in particle size and partitularly useful as the active material of the positive electrode of a lithium battery. SOLUTION: Nickel oxide particulate powder having <=50 nm average particle diameter, >=50 m<2> /g BET specific surface area and an average valence of nickel of >=2.2 is mixed with a lithium compd., 1-10 wt.% water is added to the powdery mixture and this water-contg. powdery mixture is compacted to form a compact having >=2 g/cc compacting density. This compact is fired in a flow of gaseous oxygen. |
