▎ 摘  要

NOVELTY - Anode comprises nanoporous carbon comprising graphene sheets, where the average interplanar spacing between the graphene sheets is greater than 4.4 Angstrom . USE - The anode is useful for a lithium-ion battery for portable electronics, electrification of vehicles, and high energy storage capacity grid, such as wind and solar. ADVANTAGE - The anode has increased energy/power densities, low delithiation potential, high electrical conductivity and low volume change during lithiation/delithiation, is compatible and cost-effective, minimizes the voltage variation with state of charge, exhibits high charge storage capacities and morphology, enhances diffusion channels to enable intercalations of various ionic species, and improves coulombic efficiency by co-deposition of nanoparticles.
