摘　　要：近年来,水系钠离子电池由于原材料储量丰富、安全可靠、环境友好等优势在电化学储能系统中引起了愈加广泛的关注与研究。在已报道的诸多水系钠离子电池负极材料中,具有超离子导体结构的NaTi_(2)(PO_(4))_(3)(NTP)成为最具代表性的负极材料。然而,由于NTP固有的本征电子导电性差与不可逆的“溶解-沉淀”行为阻碍了其进一步实际应用。本文综述了近几年来NTP及其复合材料作为负极材料在水系钠离子电池中的研究进展,总结了NTP改性的主要方法,包括表面修饰、尺寸形貌控制和掺杂取代,并对每种改性措施进行了详细论述。最后对NTP作为水系钠离子电池负极材料的应用前景进行了展望。In recent years,aqueous sodium-ion batteries have attracted increasing attention,and more and more research focuses on electrochemical energy storage systems due to their advantages of abundant raw materials,safety and reliability,and environmental friendliness.NaTi_(2)(PO_(4))_(3)(NTP)with a superionic conductor structure has become the most representative anode material in many reported aqueous sodium-ion batteries.However,the inherent poor electronic conductivity and irreversible dissolution-precipitation behavior of NTP have hindered its further practical application.In this work,the research progress of NTP and its composites as anode materials in aqueous sodium-ion batteries in recent years were reviewed,and the main methods of NTP modification were summarized,including surface modification,size morphology control and doping substitution.Moreover,each modification method was also discussed in detail.Finally,the application prospects of NTP as anode materials for aqueous sodium-ion batteries are proposed.
