Polymer gel electrolytes (PGEs) have been widely utilized in diverse applications including e-skins, batteries, and electrochemical displays. In particular, ion gels composed of room temperature ionic liquids (ILs) and ABA triblock copolymers with IL insoluble A blocks and a IL soluble B block are considered as promising PGEs, owing to their outstanding ionic conductivity, high capacitance, negligible vapor pressure, tunable mechanical robustness, and good solution processability. However, a trade-off between two important characteristics to evaluate electrolyte performance, ionic conductivity and mechanical property, is inevitable. Therefore, we proposed a simple but effective strategy for achieving high-performance ion gels. In addition, we functionalized ion gels to include electrochemiluminescence (ECL) and electrochromism (EC) by incorporating redox-active species, and we successfully demonstrated solution processable, low-voltage, flexible electrochemical devices.
