N-/P-doped graphene for high-performance rechargeable batteries and the origin

Distinct from pure graphene, doped graphene has been found to possess high rate capability and capacity for lithium/sodium storage. However, there has still been a lack of direct experimental evidences and fundamental understanding of the storage mechanisms at the atomic scale, which may shed a new light on the reasons of the ultrafast Li/Na storage properties and high capacity for doped graphene. In this talk, I will introduce N-doped and P-doped graphene as superb anodes for rechargeable batteries, importantly report on their atomistic insights of energy storage as revealed by building individual nanosheet battery in TEM and the density functional theory (DFT) calculations.
