Abstract
A cobalt oxide is disclosed and is represented by a chemical formula of Co1-yMyO2, wherein 0≦y≦0.9, and M is selected from the group consisting of alkali metal elements, alkaline-earth metal elements, Group-13 elements, Group-14 elements, transition metal elements, and rare-earth elements. A composite of cobalt oxide includes a cobalt oxide and an aluminum phosphate layer coated on a surface of the cobalt oxide.
Claims8
A composite of cobalt oxide comprising a cobalt oxide and an aluminum phosphate layer coated on a surface of the cobalt oxide, wherein the cobalt oxide is represented by a chemical formula of Co1-yMyO2, wherein 0<y≦0.9, and M is other than Co and selected from the group consisting of alkali metal elements, alkaline-earth metal elements, Group-13 elements, Group-14 elements, transition metal elements, and rare-earth elements, a thickness of the aluminum phosphate layer is in the range from about 5 nanometers to about 20 nanometers.
A composite of cobalt oxide consisting of a cobalt oxide, an aluminum phosphate layer coated on a surface of the cobalt oxide, and a Co—Al—O co-oxide, wherein the cobalt oxide is represented by a chemical formula of Co1-yMyO2, wherein 0<y≦0.9, and M is other than Co and selected from the group consisting of alkali metal elements, alkaline-earth metal elements, Group-13 elements, Group-14 elements, transition metal elements, and rare-earth elements.
