Antimony Oxides-Based Anode Materials for Alkali Metal-Ion Storage

With the increasing demand for renewable energy, alkali metal-ion (lithium/sodium/potassium-ion) batteries play more and more important roles in the field of static storage and electrical vehicle industry. Novel anode materials with high reversible capacity, safety and long-term cycling stability are desiderated to meet the ever-growing demand for alkali metal-ion batteries with high electrochemical performance. Antimony oxides (SbxOy) show electrochemical reaction activity with all of lithium, sodium and potassium, and are expected to be promising anode materials for alkali metal-ion storage due to their high theoretical capacities, appropriate operating potential and excellent safety properties. This review is devoted to overview the research progress on reaction mechanism and improvements in electrochemical performance of antimony oxides for alkali metal-ion storage, and look forward to their further prospects.
