Advantages and Application of Nano LTO battery

Abstract

In order to promote the development of new energy vehicles, it is very necessary to develop battery packs with high capacity and high safety performance. For achieving this goal, developing new negative electrode materials has proved to be an effective strategy. Among the many candidate materials, lithium titanate has received extensive attention due to its zero strain property. However, the size control of lithium titanate has become a very important factor to improve battery performance. By reducing the particle size, the growth of lithium dendrite can be suppressed and the ion utilization efficiency can be improved. Nanotechnology has been proved to be an effective way to create nano-scale Li₄Ti₅O₁₂. By optimizing the preparation process parameters, the size of lithium titanate can be controlled within the desired range In recent years, there are many reports about nano LTO technology. In order to have a comprehensive understanding of this field. This paper summarizes and analyzes the development status and future development direction of nanotechnology and lithium titanate battery, the application of nanotechnology in LTO such as sol-gel, molten salt, microwave, hydrothermal and solvothermal synthesis, including the latest synthesis method in recent years, and illustrated the structure-property relationship between Li₄Ti₅O₁₂ and LTO performance, which provides theoretical guidance for the development of the battery field.
