Provided is a simple, fast, scalable, and environmentally benign method of producing
graphene-embraced or encapsulated particles of a
battery electrode active material directly from a graphitic material, the method comprising: a) mixing graphitic material particles and multiple particles of a
solid electrode active material to form a mixture in an impacting chamber of an energy impacting apparatus, wherein the graphitic material has never been intercalated, oxidized, or exfoliated and the chamber contains therein no previously produced
graphene sheets and no ball-milling media; b) operating the energy impacting apparatus with a frequency and an intensity for a length of time sufficient for transferring
graphene sheets from the graphitic material to surfaces of
electrode active material particles to produce graphene-embraced
electrode active material particles; and c) recovering the particles from the impacting chamber. Also provided is a
mass of the graphene-embraced particles, electrode containing such particles, and battery containing this electrode.
