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.
