▎ 摘  要

NOVELTY - Preparation of ternary anode material containing a single crystal structure of lithium-nickel-cobalt-manganese composite oxide (I), involves dissolving lithium source, nickel source, cobalt source and manganese source in deionized water to prepare a mixed salt solution, adding carbon source as a microwave absorbing medium, to the mixed salt solution and stirring to obtain a mixed solution, placing the mixed solution in a heater for microwave heating treatment to obtain a powdery black and fluffy ternary nano-oxide precursor, and heating the ternary nano-oxide precursor. USE - Preparation of ternary anode material. ADVANTAGE - The method provides ternary anode material in short time and with low energy consumption. The ternary anode material has excellent dispersibility and cycle performance, and high compaction density. DETAILED DESCRIPTION - Preparation of ternary anode material involves dissolving lithium source, nickel source, cobalt source and manganese source in deionized water to prepare a mixed salt solution, adding carbon source as a microwave absorbing medium, to the mixed salt solution and stirring to obtain a mixed solution, placing the mixed solution in a heater for microwave heating treatment to obtain a powdery black and fluffy ternary nano-oxide precursor, and heating the ternary nano-oxide precursor. The ternary anode material comprises a single crystal structure of lithium-nickel-cobalt-manganese composite oxide of formula: LiNi1-x-yCoxMnyO2 (I), where 1-x-y is 0.5 or more, and x and y are more than 0 and less than 1.
