摘要:

钠离子电池(SIBs)具有资源丰富、成本低廉及供应风险低等优势,被认为是极具潜力的下一代电化学储能器件。目前,五氧化二钒(V2O5)正极材料因具有高工作电压及高理论容量等优点,逐渐成为SIBs正极材料的研究热点。然而,V2O5正极材料的低离子扩散系数、低电导率及反复的离子嵌入/脱嵌所致的结构不稳定等缺点,限制了其在SIBs中的应用。分析了V2O5正极材料的晶体结构和储钠机制,并通过形貌控制、晶体结构修饰、化学预插入以及与其他材料复合等改性方法,综述了V2O5正极材料在SIBs中的研究进展,最后对V2O5正极材料的发展趋势进行了展望。

关键词: V2O5, 形貌控制, 晶体结构, 化学预插入, 导电材料

Abstract:

Sodium?ion batteries (SIBs) have the advantages of rich resources and low cost and supply risk.Therefore,they are regarded as a new generation of electrochemical energy storage devices with great potential.At present,vanadium pentoxide (V2O5) has gradually become a research hotspot of cathode materials for SIBs because of its high working voltage and theoretical capacity. However,the disadvantages of V2O5 cathode material,including low ion diffusion coefficient,low conductivity,and structural instability caused by repeated ion intercalation/deintercalation,have limited its application in SIBs.This paper analyzed the crystal structure and sodium storage mechanism of V2O5 and summarized the research progress of V2O5 cathode material in SIBs through modification methods such as morphology control,crystal structure modification,chemical pre?insertion,and composition with other materials.Finally,the paper prospected the development trend of V2O5 electrode material.

Key words: V2O5, Morphology control, Crystal structure, Chemical pre?insertion, Conductive material
