▎ 摘　　要

NOVELTY - A graphene-embraced particulate comprises a single or several graphene-encapsulated primary particles of an anode active material, comprising primary particles and multiple sheets of 0.01-20 wt.% graphene material (M1) overlapped together to embrace or encapsulate the primary particles. The graphene-encapsulated primary particles along with 0-50 wt.% optional conductive additive are further embraced or encapsulated with multiple sheets of 0.01-20 wt.% graphene material (M2). Surface of material (M1) or material (M2) is in physical contact with or bonded to a chemical species forming a redox pair with lithium, chosen from sulfonate or sulfonyl-containing group, phosphate, and amine-containing group. USE - Graphene-embraced particulate is used for active material of anode for 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, and zinc-air battery (all claimed). ADVANTAGE - The graphene-embraced particulate prevents repeated direct exposure of the primary particle surface and a solid-electrolyte interface coated on the surface to the surrounding electrolyte, thus eliminating repeated breakage and re-formation of solid-electrolyte interface during repeated charging/discharging of the battery, and is obtained by economical, simple, fast, scalable, and environmentally-friendly process. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) anode electrode, which comprises the mass of multiple particulates and an optional conductive filler and binder; and (2) lithium battery. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view explaining production of graphene-embraced or graphene-encapsulated electrode active material particulate using an energy-impacting apparatus.
