  • Patent number: 10312499
    Abstract: Particles of active electrode material for a lithium secondary battery are coated with a precursor material which is either a carbon-based polymer or a metal and oxygen containing compound. The precursor material-coated particles are injected into a gas stream and momentarily exposed to an atmospheric plasma at a predetermined energy level and temperature up to about 3500° C. The plasma treatment converts (i) the carbon polymer to submicron size carbon particles or (ii) the metal compound to metal oxide particles on the surfaces of the particles of electrode material. In preferred embodiments of the invention the plasma treated coated active electrode material particles are carried by the gas stream and deposited onto an electrode material bearing substrate for a lithium battery cell.
