Abstract
A single calcination stage process for the synthesis of homogeneous crystalline lithium nickel cobalt dioxide from either a mechanical mixture of nickel and cobalt oxides, hydroxide or oxyhydroxide or a chemical precipitation of a homogeneous nickel cobalt hydroxide or cobalt nickel cobalt oxyhydroxide is provided. The reactants are calcined in the presence of lithium hydroxide and an alkali metal hydroxide under predetermined oxygen partial pressure and temperature conditions. The products of the process are characterized in having a lithium to transition metal ratio closely approximating to the desired theoretical value.
