More Information
Summary:A method of preparing a lithium nickel manganese oxide cathode material comprises the following steps of providing a precursor material, the precursor material comprises a lithium compound, a nickel compound and a manganese compound, mixing and grinding the lithium compound, the nickel compound and the manganese compound to from a cathode material precursor having a specific span value or a specific value of 90 percent particle size volume distribution (D90), (wherein the specific span value is greater than or equal to 1.0 μm and lesser than or equal to 2.0 μm, the specific value of 90 percent particle size volume distribution is greater than or equal to 0.3 μm and lesser than or equal to 0.4 μm), and processing a thermal treatment to the cathode material precursor to form the lithium nickel manganese oxide cathode material.
