▎ 摘　　要

NOVELTY - The method involves graphitizing the nano-carbon material to obtain a highly graphitized nano-carbon material. The highly graphitized nano-carbon material is mixed with molten liquid lithium, and then perform cooling treatment to obtain a nano-carbon composite lithium metal negative electrode. A nano-carbon composite lithium metal negative electrode comprises elements in mass percentage are carbon 2% to 58%, oxygen 0 to 10%, and lithium 40% to 97%. and metallic lithium is 80%-95%. USE - Method for preparing nano-carbon composite lithium metal negative electrode (claimed). ADVANTAGE - The method not only solve the problems of lithium dendrite growth and huge volume change during the charging and discharging process of the lithium metal negative electrode, but also the lithium metal negative electrode has no impurities other than carbon, and the metal lithium content is high, and the prepared negative electrode has a higher specific capacity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a nano-carbon composite lithium metal negative electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical view of an XRD spectrum of highly graphitized graphene. (Drawing includes non-English language text)
