METHOD FOR PREPARING ELECTRODE MATERIAL FOR CAPACITOR

摘要

PURPOSE: A capacitor electrode and a capacitor including the same are provided to implement high energy density by thermally processing lithium and manganese starting materials at low temperatures to minimize impurities. CONSTITUTION: Lithium starting materials are mixed with manganese starting materials. The mixed materials are thermally processed at 300 to 600 degrees centigrade for 1 to 40 hours under an air atmosphere or an oxygen atmosphere.
