  • CATHODE SYNTHESIZED BY FLUX METHOD AND BATTERY COMPRISING SAME
    Publication number: 20160043394
    Abstract: The present invention is a method for the preparation of cathode active materials, a cathode comprising the cathode active materials, and a battery comprising same. The present method comprises the step of combining metal salts and or oxides with a flux agent, and heating the mixture to at least the melting temperature of the flux agent. Cathode active materials obtained by the process of this invention have larger average particle size than the same cathode materials obtained by co-precipitation, and a higher than expected rate capability.
