Designed graphite with an activated edge for fast-charging lithium-ion storage properties.

Graphite with an activated edge is carefully designed via a controllable solution treatment and sintering process. The simultaneous existence of extra active sites and expanded layers at the edge enable it to exhibit excellent fast-charging performance in a half-cell and full-cell set-up. This work highlights an overall understanding of polarization and the optimum structure for a fast-charging anode.
