Abstract
A process for the production of LiNi.sub.1-x Mn.sub.x O.sub.2 (0.005.ltoreq..times..ltoreq.0.45) as a positive electrode active material for a nonaqueous lithium secondary cell comprising a) mixing aqueous solutions of a lithium salt, a nickel salt and manganese nitrate, b) heating with stirring the solution to dryness and c) pre-calcining from 250.degree. C. to 400.degree. C., grinding and mixing the product and finally calcining from 600.degree. C. to 900.degree. C.
