摘要

钠超离子导体(NASICON)型磷酸盐材料是一类离子传导率高、结构稳定性高、晶体结构多样的钠离子电池正极材料,Na3V2(PO4)3(NVP)作为典型的NASICON型正极材料,因其独特的电化学性能与优异的循环稳定性而受到研究人员的广泛关注,但是NVP较低的电导率、原材料的高毒性和高成本等缺陷限制了其进一步发展与应用.对NASICON型磷酸盐正极材料的国内外研究工作进行了系统分析,总结了不同的制备方法和改性方式对NVP结构特性和储钠性能的影响,以期通过调整合成工艺、掺杂改性、表面包覆等优化手段,进一步提升NASICON型钠离子电池正极材料的电化学性能,进一步推进钠离子电池商业化发展进程.

Abstract

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.
