Research Progress on NASICON-Type Na3V2(PO4)3 Cathode Materials for SIBs
Na super-ionic conductor(NASICON)type phosphate material is a kind of cathode material for sodium ion battery with high ionic conductivity,high structural stability and diverse crystal structure.Na3V2(PO4)3(NVP),as a typical NASICON-Type cathode,has attracted much attention due to its unique electrochemical properties and excellent cyclic stability.However,the low conductivity of NVP,high toxicity and high cost of raw materials limit its further devel-opment and application.In this paper,the research work on NASICON-Type phosphate cathode materials at home and abroad was systematically analyzed,and the effects of different preparation methods and modification methods on the structural characteristics and sodium storage performance of NVP were summarized,in order to further improve the elec-trochemical performance of NASICON-Type cathode for SIBs and further promote the commercialization of SIBs by ad-justing the synthesis process,doping modification,surface coating and other optimization methods.
