摘　　要：钠离子电池因其与锂离子电池相似的充放电机理和构造,以及钠资源丰富且价格低廉而备受瞩目。因此,钠离子电池被认为是锂离子电池的最佳替代品之一,可广泛应用于储能系统、两轮电动车和低速电池等领域,有望为解决锂资源短缺问题提供可行的替代方案。正极材料作为钠离子电池的关键材料之一,受到了广泛关注。其中橄榄石型NaFePO_(4)由于其稳定性好、安全性佳、容量高的优势,被认为是一种良好的钠离子电池正极材料。然而目前橄榄石型NaFePO_(4)的研究受限于其合成方法,阻碍了橄榄石型NaFePO_(4)的深入研究。因此,文章从特性、合成方法、机理三个方面对橄榄石型NaFePO_(4)材料进行总结和评述,并对其提出了展望。Sodium-ion batteries have attracted attention due to their similar charging and discharging mechanisms and structures to lithium-ion batteries,as well as abundant sodium resources and low prices.Therefore,sodium-ion batteries are considered one of the best alternatives to lithium-ion batteries and can be widely used in energy storage systems,two-wheeled electric vehicles,low-speed batteries,and other fields.They are expected to provide feasible alternatives to address the shortage of lithium resources.As one of the key materials for sodium-ion batteries,positive electrode materials have attracted widespread attention.Among them,olivine-type NaFePO_(4)is considered a promising positive electrode material for sodiumion batteries due to its good stability,excellent safety,and high capacity.However,current research on olivine-type NaFePO_(4)is limited by its synthesis methods,which hinders in-depth research on olivine-type NaFePO_(4).Therefore,this article summarizes and reviews the characteristics,synthesis methods,and mechanisms of olivine-type NaFePO_(4)materials,and proposes prospects for its development.
