  • Method for preparing a cathode material for lithium secondary battery
    Patent number: 8973852
    Abstract: Disclose is a method for preparing a cathode material for a lithium secondary battery, the method comprising the steps of: preparing an amorphous silicon oxide; using the prepared silicon oxide as a starting material; and milling the amorphous silicon oxide, a lithium silicon oxide and a transition metal silicon oxide at a predetermined ratio, drying the milled material, and heat-treating the dried material in an atmosphere of inert gas, thereby preparing a lithium transition metal silicon oxide.
    Type: Grant
    Filed: October 17, 2012
    Date of Patent: March 10, 2015
    Assignee: Institute for Advanced Engineering
    Inventors: Hyun Soen Hong, Yun-Ho Jin, Kun Jae Lee
