The increasing demand for high-performance energy storage devices has stimulated interest in advanced electrolyte materials. Among them, ionic liquids (ILs) stand out for their thermal stability, wide electrochemical windows, and good ionic conductivity. When doped into polymeric matrices, these ionic liquids form hybrid polymeric electrolytes that synergize the benefits of both liquid and solid electrolytes. This study explores a polymeric electrolyte based on polyethylene oxide (PEO) doped with tributylmethylphosphonium iodide (TMPI) and ammonium iodide (NH4I), focusing on its synthesis, structural and electrical properties, and performance in energy storage devices such as dye-sensitized solar cells and supercapacitors. Strategies to improve its ionic conductivity, mechanical and chemical stability, and electrode compatibility are also discussed, along with future directions in this field.
对高性能储能设备日益增长的需求激发了人们对先进电解质材料的兴趣。其中，离子液体（ILs）因其热稳定性、宽电化学窗口和良好的离子导电性而脱颖而出。当这些离子液体掺杂到聚合物基体中时，会形成混合聚合物电解质，兼具液体和固体电解质的优点。本研究探索了一种基于聚环氧乙烷（PEO）并掺杂碘化三丁基甲基鏻（TMPI）和碘化铵（NH4I）的聚合物电解质，重点研究其合成、结构和电学性能，以及在染料敏化太阳能电池和超级电容器等储能设备中的性能。还讨论了提高其离子导电性、机械和化学稳定性以及电极兼容性的策略，以及该领域的未来发展方向。
