| Abstract |
Titanium niobium oxide (TiNb2O7) has received a great deal of attention in lithium-ion battery (LIBs) because of its high theoretical capacity, environmentally benign nature, and good cycling stability. However, TiNb2O7 suffers from limited rate capability due to low Li+ ion diffusivity and poor electronic conductivity. In this study, we designed a new synthesis route to prepare monodisperse, mesoporous TiNb2O7 microspheres that can mitigate these limitations. Delicate control over annealing temperature offers a way to manipulate the grain size and specific surface area of TiNb2O7 microspheres, and our investigation revealed there was a compromise between these structural parameters the LIB performance of TiNb2O7 microspheres. This highlights the importance of gaining a comprehensive understanding of the critical factors governing the electrochemical behaviour of TiNb2O7 to establish a design principle for advanced electrode materials. |
