Abstract:

Lithium-ion energy storage devices have shown great potential in the fields of large-scale energy storage and new energy vehicles due to their high energy density and environmental friendliness. However, due to the unsatisfactory electrochemical kinetics and safety issue at high rates of traditional anode materials such as graphite and silicon, lithium-ion batteries cannot meet the current increasing requirements of fast charging and discharging. Therefore, it is significant to develop anode materials with fast insertion/de-insertion kinetics of lithium ions, excellent safety and good stability. Compared with traditional anode materials, niobium-based oxides have the advantages of suitable theoretical capacity, safer working potential and fast ion transport channels. This review summarizes the latest progress on niobium-based oxide anode materials for ultrafast lithium ion storage devices, focusing on the lithium storage mechanism and various modification strategies of niobium-based oxides. In the end, the future development directions and challenges of niobium-based oxide materials will be presented.

Key words: Niobium-based oxide, Anode material, High rate performance, Modification method
