A PROCESS FOR THE SYNTHESIS OF LITHIUM ALUMINIUM COBALTITE (LIAL0.5CO0.5O2) USEFUL AS CATHODE MATERIAL FOR REVERSIBLE LITHIUM ION CELLS

摘要

The present invention relates to the process for the preparation of lithium aluminum cobaltite as a useful cathode material for lithium cells. The product is a composite which is very useful for high voltage lithium reversible cells and can be prepared by mixing oxides of aluminum, cobalt with lithium hydroxide by heating together all in solid state condition. The mixture was made into paste by adding necessary quantity of glycerol and the paste was calcined at 750 deg C. LiAlo.s CO0.5 O2 is a reversible cathode material useful for high voltage cells of lithium in no aqueous media.
