Abstract: Olivine lithium manganese iron phosphate is made in a coprecipitation process from a water/alcoholic cosolvent mixture. The LMFP particles so obtained exhibit surprisingly high electronic conductivities, which in turn leads to other advantages such as high energy and power densities and excellent cycling performance.

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.

Abstract: A method for forming lithium metal oxides comprised of Ni, Mn and Co useful for making lithium ion batteries comprises providing precursor particulates of Ni and Co that are of a particular size that allows the formation of improved lithium metal oxides. The method allows the formation of lithium metal oxides having improved safety while retaining good capacity and rate capability. In particular, the method allows for the formation of lithium metal oxide where the primary particle surface Mn/Ni ratio is greater than the bulk Mn/Ni. Likewise the method allows the formation of lithium metal oxides with secondary particles having much higher densities allowing for higher cathode densities and battery capacities while retaining good capacity and rate performance.

Abstract: A battery electrolyte solution contains a lithium salt, diethyl carbonate and at least one of 4-fluoroethylene carbonate and ethylene carbonate. This battery electrolyte is highly stable even when used in batteries in which the cathode material has a high operating potential (such as 4.5V or more) relative to Li/Li+. Batteries containing this electrolyte solution therefore have excellent cycling stability.
