ABSTRACT:
The invention relates to a method for preparing multiple metal oxides and intermediate compound, i.e. spherical nickelous hydroxide which is lopped. The intermediate compound is prepared by: mixing bivalent nickel salt, cobalt salt, ammonia water and ammonium salt to form solution containing complex; then adding the said solution containing complex with the mixture solution of metal salt(s) and alkali into reaction vessel in parallel flow, stirring to form precipitate of spherical nickelous hydroxide which is dopped, and washing to remove the impurities. The resulting spherical nickelous hydroxide which is dopped, as an intermediate compound, can be used to produce multiple metal oxides. The resulting multiple metal oxides can be used as anode active material. The spherical nickelous hydroxide has advantages of uniform size and narrow size distribution. The multiple metal oxides has high electric conductivity and cycle performance, particularly, is suitable to be used as anode material.
