Abstract:
A method for making a lithium battery cathode composite is provided. First, a plurality of lithium vanadium phosphate particles is provided. A lithium iron phosphate layer is then formed on an outer surface of each of the lithium vanadium phosphate particle by coating a lithium iron phosphate precursor slurry, thereby forming the lithium battery cathode composite.
