摘　　要：针对水系Na电池性能问题,提出了一个新的替代方案。采用聚丙烯腈(PAN)为载体,通过复合无机盐Na2SiO3,使用相转移法制备固态电解质材料,并对新电解液体系的电化学性能通过交流阻抗、循环伏安法、充放电循环等方法进行了测试。结果表明,相转移法可以将钠盐复合于聚合物中,且其中的钠离子可以完成传输,与水系电解液相比,2种电池性能相近,因此,PAN复合Na2SiO3完全可以作为水系钠电池的替代体系,并解决了水溶剂在高电压下分解的问题,具有很好的应用前景。This study proposed a new alternative to the performance of water-based sodium-ion batteries.The solid electrolyte material was prepared by phase transfer method using PAN as carrier.The electrochemical properties of the new electrolyte system were tested by AC Impedance,Cyclic Voltammetry,charge-discharge cycle and other methods.The results show that the phase transfer method can composite the sodium salt into the polymer,and the sodium ion can be transported.Compared with the aqueous electrolyte,the performance of the two batteries is similar.Therefore,the PAN composite Na2SiO3 can be used as the water sodium battery.It replaces the system and solves the problem of decomposition of water solvent at high voltage,and has a good application prospect.
