Extremely Weak van der Waals Coupling in Vertical ReS₂ Nanowalls for High‐Current‐Density Lithium‐Ion Batteries

Abstract

The synthesis of vertical ReS2 nanowalls on 3D graphene foam (V-ReS2 /3DGF) is demonstrated by a chemical vapor deposition route. The vertical nanowall structure leads to an effective exposure of active sites and enhances the lithium interaction with all of the layers. When serving as the anode material for lithium-ion batteries, the V-ReS2 /3DGF composite demonstrates excellent cycling stability at high-current-density.
