Abstract:
A method of manufacturing active material of Formula 1 for a positive electrode used in lithium secondary batteries comprising the steps of:adding a chelating agent to a mixture derived by dissolving lithium salt, nickel salt and cobalt salt in a solvent to a molar ratio of 0.95-1.06:0.5-1:0-0.5;producing a gel by heating the mixture;forming an organic-inorganic precursor by thermally decomposing the gel; andheat treating the precursor.Li.sub.x Ni.sub.1-y Co.sub.y O.sub.2 [Formula 1]where x is between 0.95 and 1.06, and y is between 0 and 0.5.
