<p>This invention relates to a process for producing an improved powder for the positive electrode of lithium ion batteries wherein the powder comprises lithium, vanadium and phosphate. The process includes forming a suspension of the precursors with a high boiling temperature solvent and heating the suspension to a reaction temperature of between 250° C. and 400° C. to convert the precursors to the desired solid product. The solid product is separated from the suspension and is heated to a higher temperature to crystallize the product. The resulting product retains a small particle size thus avoiding the need for milling or other processing to reduce the product to a particle size suited for batteries.</p> |
