英文摘要Transition metal oxides as anode materials for lithium ion batteries (LIBs) generally suffer from significant capacity fading due to their chemical and mechanical degradations upon extended cycling. In this work, a three-dimensional (3D) ordered hierarchically porous amorphous hybrid based on vanadium oxide and molybdenum oxide (3D-OHP-a-VOx/MoOy) was first constructed and investigated as an ideal anode material for LIBs. The valence states of V and Mo in this hybrid were determined by X-ray absorption near-edge structure (XANES) measurements. The as-synthesized 3D-OHP-a-VOx/MoOy exhibits significantly improved lithium storage performance in terms of specific capacity, cycling stability, and rate capability compared to single-component a-VOx, a-MoOy, and highly crystalline VOx/MoOy hybrid (c-VOx/MoOy). The enhanced lithium storage performance of 3D-OHP-a-VOx/MoOy probably benefits from its amorphous nature, synergistic effect between a-VOx and a-MoOy, and 3D hierarchically porous structure. To the best of our knowledge, our result is the best among the as-reported molybdenum oxides and vanadium oxides for energy storage applications. This strategy in the current work offers a new perspective in designing high-performance anode materials for LIBs.
