METHOD OF MAKING ACTIVE MATERIALS FOR USE IN SECONDARY ELECTROCHEMICAL CELLS

摘要

The present invention provides for the two step preparation of lithium vanadium phosphate by pre-treatment of a mixture of precursor materials via high pressure at relatively low temperatures in water (hydrotherma!pretreatment) and then calcining such hydrothermally pretreated precursors at relatively high temperatures for a period of time sufficient to produce lithium vanadium phosphate. The lithium vanadium phosphate so produced finds use in producing electrodes for electrochemical cells.
