▎ 摘  要

NOVELTY - The material has a graphene tie-layer arranged in a nanofiber. A nanofiber surface is arranged with the nanofiber that is made of metal or alloy. The graphene tie-layer is made of graphene that is selected among oxidation graphene (graphene oxide) or reduction oxidation graphene. The metal is made of silicone, germanium, aluminum, antimony, tin, titanium, vanadium, chrome, cobalt, nickel, manganese, iron, zinc, copper, lithium, semi-metal, post-transition metal, transition metal, alkali metal or sodium. Diameter of a carbon nano fiber is 1nm-1 micro meter. USE - Anodal active material for a lithium-ion secondary battery. ADVANTAGE - The material minimizes growth of a SEI film generated in the nanofiber surface and suppresses charge transfer resistance increase in an effective manner. The material has high conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a negative active material. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of an anodal active material.
