Abstract: Aspects of the invention are based on the discovery that cathode materials and lithium ion batteries comprising the cathode material, having improved thermal stability may be produced from a cathode material that is comprised of a mixture of a lithium metal oxide and a lithium metal phosphate wherein the lithium metal phosphate comprises a volume fraction of secondary particles having a size of 0.1 to 3 μm that is from 5 to 100%, based on the total content of lithium metal phosphate. More specifically cathodes comprising lithium metal phosphates having the recited secondary particle ranges help provide cathode materials that are capable of passing the nail penetration test without generating smoke or flames. Methods of forming the cathode and lithium ion battery comprising the cathode are also provided.
