▎ 摘　　要

NOVELTY - Direct-transfer method of producing graphene-embraced or graphene-encapsulated electrode active material directly from graphitic material is performed by successively performing step (a) of mixing multiple particles of graphitic material and multiple particles of solid electrode active material to form mixture in impacting chamber of energy impacting apparatus, and step (b) of operating energy impacting apparatus. USE - Direct-transfer method of producing graphene-embraced or graphene-encapsulated electrode active material for electrode used for battery e.g. lithium-ion battery, lithium metal secondary battery, lithium-sulfur battery, lithium-air battery, lithium-selenium battery, sodium-ion battery, sodium metal secondary battery, sodium-sulfur battery, sodium-air battery, magnesium-ion battery, magnesium metal battery, aluminum-ion battery, aluminum metal secondary battery, zinc-ion battery, zinc metal battery, or zinc-air battery (all claimed). ADVANTAGE - The method has low environmental impact, short process time, low energy consumption, and low degree of graphene oxidation, and is cost effective and simple. The method produces graphene-embraced or graphene-encapsulated electrode active material which improves battery cycle life and battery performance. DETAILED DESCRIPTION - Direct-transfer method of producing graphene-embraced or graphene-encapsulated electrode active material directly from graphitic material is performed by successively performing step (a) of mixing multiple particles of graphitic material and multiple particles of solid electrode active material to form mixture in impacting chamber of energy impacting apparatus, in which graphitic material is never intercalated, oxidized, or exfoliated and impacting chamber contains no previously produced isolated graphene sheets and no ball-milling media other than multiple particles of solid electrode active material, step (b) of operating energy impacting apparatus with frequency and intensity for length of time sufficient for peeling off graphene sheets from particles of graphitic material and transferring peeled graphene sheets to surfaces of solid electrode active material particles to fully embrace or encapsulate particles to produce particles of graphene-embraced or graphene-encapsulated electrode active material inside the impacting chamber, and step (c) of recovering particles of graphene-embraced or graphene-encapsulated electrode active material from impacting chamber. INDEPENDENT CLAIMS are included for: (1) mass of graphene-embraced particles of solid active material, in which graphene proportion is 0.01-20 wt.% based on total weight of graphene and solid active material particles combined; (2) battery electrode containing graphene-embraced or graphene-encapsulated electrode active material; and (3) battery containing the battery electrode.
