Theoretical study of electrode materials for sodium ion batteries based on Graphether/Graphene heterostructure

Abstract

The graphether/graphene vdW heterostructure has been systematically studied as an electrode material for sodium batteries based on density functional theory. We predict that the graphether/graphene heterostructure exhibits low diffusion barrier and large capacity. All these calculation results suggest that the graphether/graphene heterostructure can be used as a future commercial anode material for sodium ion batteries.
