Abstract
Methods are described for the low temperature preparation of the spinel LiMn.sub.2 O.sub.4 and layered LiCoO.sub.2 phases which are intercalable compounds of interest for use in lithium secondary batteries. These phases can be prepared in bulk or thick film form at temperatures less than 400.degree. C. using acetate precursors.
