Cathode composite material synthesis having high energy density for lithium secondary battery for electric vehicle and electrode manufacturing technology thereof
Abstract:
The present invention relates to the manufacture of a high capacity electrode by synthesizing an excellent Li2MnO3-based composite material Li(LixNiyCozMnwO2) to improve the characteristics of an inactive Li2MnO3 material with a specific capacity of about 460 mAh/g. Here, a manufacturing method of a cathode material for a lithium secondary battery uses a Li2MnO3-based composite material Li(LixNiyCozMnwO2) by reacting a starting material wherein a nickel nitrate solution, a manganese nitrate solution and a cobalt nitrate solution are mixed, with a complex agent by co-precipitation.
