摘　　要：磷酸钛钠[NaTi_(2)(PO_(4))_(3)]具有NASICON稳定结构,超大规格的三维开放式架构,显著的能量密度及稳定性,成为当前水系钠离子电池(aqueous sodium-ion batteries,ASIBs)热门研究的负极材料。但NaTi_(2)(PO_(4))_(3)在ASIBs中存在导电性差、与水易发生副反应以及材料溶解等诸多问题。为克服上述问题,通常采用纳米化、碳包覆和元素掺杂等方式解决上述问题,从而优化材料性能,使其具有高电导率和长循环性能。从NaTi_(2)(PO_(4))_(3)材料的结构、改性方法及电化学性能等方面进行综述,以加深对NaTi_(2)(PO_(4))_(3)结构改善和性能优化技术路径与方法的了解。NaTi_(2)(PO_(4))_(3) has a NASICON stable structure,an ultra-large three-dimensional open architecture,significant energy density and stability,and has become a hotly researched anode material for aqueous sodium-ion batteries(ASIBs).However,NaTi_(2)(PO_(4))_(3) has many problems in ASIBs,such as poor conductivity,side effects with water,and material dissolution.In order to overcome the above problems,nano-materialization,carbon covering,and element doping was usually used to solve the above problems,so as to optimize the performance of the material and make it have high-conductivity and long-cycle performance.This article reviewed the structure,modification method and electrochemical performance of NaTi_(2)(PO_(4))_(3) materials to deepen the understanding of the improvement of the NaTi_(2)(PO_(4))_(3) structure and the performance optimization technical path and method.
