▎ 摘  要

NOVELTY - Preparing lithium ion material anode comprises (i) mixing ternary precursor and lithium source, calcining, crushing and sieving to obtain matrix ternarity anode A, (ii) mixing the matrix anode, molybdenum source and graphene oxide to obtain mixed material B, sequentially sintering in atmosphere containing sulfur source and inert atmosphere to obtain powder C, and (iii) mixing sintered powder C with poly-N-isopropylacrylamide to obtain final product. USE - The method is useful for preparing lithium-ion material anode, which is useful in preparing lithium-ion battery (claimed), and improving direct current internal resistance of battery in automobile and electronic industry. ADVANTAGE - The lithium ion material anode has high energy density, high compaction density, simple preparation process and high cyclic DCR growth rate, and reduces the material surface residual alkali. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a lithium ion battery.
