Nanoporous carbon as an anode material for Li-ion batteries
| DWPI Title: Anode useful for lithium-ion battery for portable electronics, electrification of vehicles, and high energy storage capacity for grid, comprises nanoporous carbon comprising graphene sheets |
| Abstract: Nanoporous carbon provides a binderless, three-dimensional form of graphene as an anode material for lithium-ion batteries. |
| 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. |
| Novelty: Anode comprises nanoporous carbon comprising graphene sheets, where the average interplanar spacing between the graphene sheets is greater than 4.4Å . |
