Polymer-based solid electrolytes have good prospects in the arena of sodium-metal batteries (SMBs) because of their high stability and safety. However, it has problems, including insufficient ion conductivity and narrow voltage windows, which may reduce performance and hinder its practical application. The existing research has not thoroughly investigated the problem of poor ionic conductivity in solid polymer electrolytes (SPEs). This review focuses on improving the low ionic conductivity of SPEs. A comprehensive approach is proposed, which includes the introduction of inorganic fillers, the dissociation of different salts, and the electrode/electrolyte interface affinity regulation. At last, we presented several crucial prospects for promoting the future progress of SPEs and SMBs.
基于聚合物的固体电解质因其高稳定性和安全性在钠金属电池（SMBs）领域具有良好的前景。然而，它存在一些问题，包括离子电导率不足和电压窗口狭窄，这可能会降低性能并阻碍其实际应用。现有研究尚未对固体聚合物电解质（SPEs）中离子电导率差的问题进行深入研究。本综述着重于提高SPEs的低离子电导率。提出了一种综合方法，包括引入无机填料、不同盐的解离以及电极/电解质界面亲和力调控。最后，我们提出了几个推动SPEs和SMBs未来发展的关键展望。
