Ultrathin layered nanomaterials show promising advantages to promote the Li+ diffusion kinetics, however, the self-aggregation/stacking of nanomaterials lead to large capacity loss and limited rate capability, which urgently needs to be addressed. Herein, we report a three-dimensional (3D) novel vanadium oxide (H2V3O8) hydrogel nanostructure composed of intertwined ultrathin nanoribbons and self-coiled...
High-speed electron transfer channels and short Li ion transport distance are beneficial to improvement of Li ion battery properties. Here, a two-step solution phase synthesis method is developed to construct the V 2 O 5 quantum dots/graphene hybrid nanocomposite by controlling nucleation and growth processes. It is demonstrated that the V 2 O 5 quantum dots with an...
