ABSTRACT:
A lithium secondary battery comprising a positive electrode a double oxide of lithium and nickel wherein said double oxide is formed by burning a mixture of a nickel compound such as nickel carbonate, and a lithium compound such as lithium nitrate, at an atomic ratio of Li/Ni of from >1.0 to 1.4, in either air or oxygen, and a method of manufacturing the same.
