Abstract

Polymerized ionic networks (PINs) with six ion pairs per repeating unit are synthesized by nucleophilic-substitution-mediated polymerization or radical polymerization of monomers bearing six 1-vinylimidazolium cations. PIN-based solid-like electrolytes show good ionic conductivities (up to 5.32 × 10(-3) S cm(-1) at 22°C), wide electrochemical stability windows (up to 5.6 V), and good interfacial compatibility with the electrodes.

Keywords: ionic conductivity; ionic polymers; poly(ionic liquid)s; solid electrolytes.
