Abstract

Abstract : An efficient bottom‐up approach is demonstrated toward hybrid 2D–0D graphene–vanadium nitride (VN) quantum dots with homogeneous dispersion of VN onto graphene, multiporous structure, and continuous graphene backbone. Such unique structures efficiently prevent the aggregation of VN and accommodate their volume changes, and also facilitate the fast diffusion of lithium and electron, rendering a significant improvement in electrochemical activities for lithium and sodium storage.
