ABSTRACT:
A method of preparing Li.sub.x Mn.sub.2 O.sub.4 for a secondary battery includes mixing lithium nitrate, magnanese nitrate and citric acid. A complex citrate solution is formed in the substantial absence of a polyhydroxyl alcohol. The complex citrate solution is dehydrated to produce a precursor. The precursor is then heated at a substantially constant rate and then calcined to provide a spinel compound.
