We report the synthesis of a Na-ion-conducting ionogel (IG) electrolyte using a one-pot, siloxane-modified sol–gel approach. The resulting pseudosolid electrolyte provides a nonflammable alternative to traditional carbonate liquids and demonstrates a wide stability window (5 V) as well as a high room-temperature ionic conductivity (∼1 mS cm^–1). The IG exhibits excellent interfacial properties in contact with both negative and positive Na⁺ electrodes, enabling the operation of a solid-state sodium-ion battery.

硅氧烷改性的，基于二氧化硅的离子凝胶作为钠离子电池的伪固体电解质

我们报告了使用一锅法，硅氧烷改性的溶胶-凝胶法合成导电钠离子的离子凝胶（IG）电解质。所得的伪固体电解质提供了传统碳酸盐液体的不易燃替代品，并显示出宽广的稳定性窗口（5 V）和较高的室温离子电导率（〜1 mS cm ^–1）。IG在与负极和正极Na ⁺电极接触时均表现出出色的界面性能，从而可以使固态钠离子电池运行。
