摘要Development of three-dimensional ternary vanadate compounds with excellent structural stability on exfoliated graphene nanoflacks allows the first success of conversion-type sodium vanadate anode candidate for high-rate and long-life lithium-ion batteries(LIBs). Corresponding additive-free self-anchoring behavior of active sodium vanadates material on graphene surface is representatively investigated, architecturing unique dendritic structure, a first-of-this-kind configuration, with robust flexibility and sufficient capability of structure-preservation. The prepared nanocomposite provides a high reversible capacity over 800 mA h g(-1) and ultrafast charging/discharging capability with Li-ions via conversion-type reaction. More remarkably, the well-designed structure retains more than 96% of initial capacity with respect to their ultralong cycling stability, demonstrating the combined advantages of the facile hydrothermal protocol, high active material loading and architecture configuration for high-performance Li-ions storage. As a consequence, this research reveals the importance and effectiveness of self assembling sodium vanadates on graphene nanoflakes with 3D hierarchial structure and indicates the significant potential of developing ternary vanadate compounds as promising anode candidate for LIBs.
