【 摘 要 】

In this work, we report a new diglyme-based gel-polymer electrolyte (DOKBn-GPE) suitable for the realization of a potassium-ion capacitor (KIC). We show that this novel gel polymer electrolyte displays good mechanical stability, high ionic conductivity (2.84 mS cm-1 at 20 degrees C), and broad electrochemical stability (> 5.0 V). Its use in KIC makes possible the realization of devices displaying high energy density and high stability during pro-longed charge-discharge as well as during float tests. These results are indicating that the development of diglyme-based GPEs is a promising strategy for the application of high-performance K-based energy storage devices.
