  • IMPROVED LITHIUM METAL OXIDE CATHODE MATERIALS AND METHOD TO MAKE THEM
    Publication number: 20160315315
    Abstract: A coated cathode material comprises a lithium metal oxide particulate having a surface at least partially coated with a coating comprised of a complex metal oxide of aluminum and a second metal that is lanthanum, yttria or combination thereof. The coated cathode material may be made by providing a lithium metal oxide particulate which is then contacted with a precursor compound that forms a complex metal oxide upon heating. The coated lithium metal oxide is then heated to a temperature sufficient to form the complex metal oxide, wherein the complex metal oxide is amorphous and contains aluminum and a second metal that is lanthanum, yttria or combination thereof and the complex metal oxide is bonded to the lithium metal oxide.
