▎ 摘　　要

NOVELTY - Multiple porous graphene particulates production involves preparing a graphene dispersion having multiple primary particles of the anode active material and multiple sheets of a starting graphene material dispersed in a liquid medium. The starting graphene material is selected from a pristine graphene, graphene oxide, reduced graphene oxide, graphene fluoride, graphene chloride, graphene bromide, graphene iodide, hydrogenated graphene, nitrogenated graphene, chemically functionalized graphene, or their combination. The dispersion contains a blowing agent having a blowing agent-to-graphene material weight ratio of 0.01:1.0-1.01.0. The graphene dispersion is dispensed, formed and dried into multiple droplets containing graphene sheets. The droplets are heat treated at 80-3200 degrees C to induce volatile gas molecules from the non-carbon elements or to activate the blowing agent for producing the multiple porous graphene particulates. USE - Method for producing multiple porous graphene particulates for a lithium battery anode. ADVANTAGE - The method produces the multiple porous graphene particulates in a simple, cost-effective and eco-friendly manner with significantly improved anode layer to provide robust three-dimensional network of electron-conducting pathways and high conductivity, and battery with long-term cycling stability. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the porous graphene particulate-protected anode active material.
