▎ 摘　　要

NOVELTY - Coated modified lithium-ion battery anode material comprises core layer covered with shell layer. The core layer is copper sulfide (CuS) composite reduced graphene. The shell layer is thermosetting resin having decomposing temperature greater than 180 degrees C. USE - Coated modified lithium-ion battery anode material. ADVANTAGE - The material has enhanced electron transfer rate, reduces amount of current, heat, and thermal isolation, extends battery life, does not cause battery large electrochemical performance, and suppresses volume expansion of material core layer. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of material comprising adding core material into high speed mixer, and stirring at 100-450 revolutions/minute (rpm); dispersing or dissolving thermosetting resin in ethanol or acetone to obtain emulsion or solution, adding into sprayer, spraying emulsion or solution at 0.5-3 mu m on nuclear material, continuously stirring at 100-450 rpm for 30 minutes to 3 hours, and curing at 80-120 degrees C for 3-5 hours.
