  • Method for preparing cathode active material
    Patent number: 8795550
    Abstract: A method for preparing a cathode active material includes mixing a phosphorus source material, a lithium source material, and a dispersing agent together to form a first liquid mixture. An iron powder is added into the first liquid mixture. The first liquid mixture with the iron powder therein is dried to achieve a precursor. The precursor is calcined in a protective gas at a temperature of about 600° C. to about 800° C. for more than about 2 hours.
    Type: Grant

  • Method for making metal sulfide nanocrystals
    Patent number: 8211399
    Abstract: A method for making metal sulfide nanocrystals is provided. First, some metal salt powders are provided in a container. Second, superfluous mercaptan is added into the container. Then the superfluous mercaptan and the metal salt are stirred uniformly to get a precursor mixture and the precursor mixture is heated to get the metal sulfide nanocrystals. Lastly, the metal sulfide nanocrystals are separated and washed.
