PROCESS FOR MANUFACTURING LITHIUM ION SECONDARY BATTERY ELECTRODE COMPOUNDS

摘要

Provided is a method of preparing a cathode material for lithium ion cell, which is designed to have the cycle characteristic enhanced and high initial discharge capacity, by synthesizing LiMn2O4 powder having a stable spinel structure, vigorously agitating the powder in an aqueous solution of Li and Ni ions, dispersing the solution through a supersonic wave treatment, filtering it so as for the powder to adsorb the ions, and performing a heat treatment for doping the ions.
