New Diglyme-based Gel Polymer Electrolytes for Na-based Energy Storage Devices.

This work presents for the first time a new diglyme-based gel polymer (DOBn-GPE) suitable for Na-based energy storage devices. The DOBn-GPE, which contains a methacrylate-based polymer, exhibited an excellent high ionic conductivity (2.3 mS cm at 20 °C), broad electrochemical stability (>5.
