Abstract
An improved method of making a cathode for use in a lithium ion battery is comprised of mixing a lithium metal oxide and lithium metal phosphate in a solvent, where both of these are comprised of primary particles that have been agglomerated into secondary particles of particular size and mixing is insufficient to break up the particles of the lithium metal phosphate, coating the mixture of step (A) on to a metal foil and removing the solvent to form the cathode. The lithium metal oxide is also desirably not broken either. The cathode may be one that has lithium metal oxide and a particular lithium metal phosphate wherein the majority of the metal is Mn.
