Claims10
A lithium battery positive material, comprising lithium nickel manganese oxide doped with copper, titanium, nitrogen, and carbon.
A manufacturing method for manufacturing a lithium battery positive material, the manufacturing method comprising:
- using a copper source, a titanium source, and lithium nickel manganate powder to form a precursor of lithium nickel manganese oxide doped with copper and titanium by performing a co-precipitation method, a filtration process, and a sintering process;
- and
- mixing the precursor of the lithium nickel manganese oxide doped with copper and titanium with a carbon source, and coating a nitrogen source by a supercritical fluid extraction method to obtain the lithium nickel manganese oxide doped with copper, titanium, nitrogen, and carbon.
