摘要


Niobate has become an advanced anode material that can be used in lithium-ion batteries due to its higher voltage and the presence of multiple single-electron redox pairs relative to lithium, which will result in higher capacity and better safety. However, because of the electron distribution of the internal elements, it causes problems such as low conductivity. Therefore, at this stage, researchers have been carried out to solve this problem. This paper takes TiNb_xO_(2.5x+2) (x=2, 10 or 14) anode material as the main object of discussion, and discusses the application of TiNb_xO_(2.5x+2) in lithium-ion batteries as well as the modification strategy.
