Abstract: NASICON-type phosphates are known as the high-performance electrode materials for sodium-ion batteries application. Especially, the robust 3D framework facilitates fast Na+ transportation with large radius. However, the disadvantages, including high molecular weight and insulating nature, strongly limits their practical applications. In recent year, our group focus on the synthesis of NASICON-type materials, e.g. Na3V2(PO4)3, NaTi2(PO4)3, Ca0.5Ti2(PO4)3, Na2VTi(PO4)3, and the study of their electrochemical properties as the negative electrode for sodium-ion batteries. These results not only hold prospects for multifunctional design of new materials, but also demonstrate the potential applications for next-generation clean energy strategies.
