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.
