▎ 摘　　要

NOVELTY - A composition of material comprises an electroconductive three-dimensional (3D) aggregate formed using graphene sheet and sintered together to define a three-dimensional hierarchical open porous structure comprising mesoscale structuring in combination with micron-scale fractal structuring and configured to provide an electrical conduction between contact points of the graphene sheets, and a porous arrangement formed in the three dimensional hierarchical open porous structure and arranged to contain a liquid electrolyte configured to provide ion transport through interconnected porous channel(s) in the porous structure, where the respective porous channel of porous channel(s) comprising a portion (p1) configured to provide tunable ion conduits, a portion (p2) configured to facilitate rapid ion transport, and a portion (p3) configured to at least partially or temporarily confine active material. The material is nucleated from homogenous nucleation. USE - Composition of material used for forming self-assembled binder-less mesoporous carbon-based particles. Uses include but are not limited to lithium-ion battery for electronics, telecommunication, computing, networking, power devices, printable computing, composites, and tire. ADVANTAGE - The composition of material provides the battery having excellent specific capacity, cycling performance, and Coulombic efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of three-dimensional self-assembled binder-less three-dimensional mesoporous carbon-based particle having tunable electrical pathways and ionic conduits throughout the thickness at various magnification level.
