The single‐Li+ conduction of the cross‐linking poly [oligo (oxyethylene) methacrylate‐co‐lithium methacryloyl hexylsulfonate]s was studied, and an Li+ ionic transport number of 0.994 estimated from the isothermal transient ionic current (ITIC), in which an ion‐blocking platinum electrode was used. The results show that Li+ ‐ionic conduction can be reasonably described by Vogel–Tammann–Fulcher (VTF) equation, suggesting that there is close correlation between ionic migration and segmental motion in these polymers. The battery composed of lithium/this copolymer film/polyaniline supplied a constant short circuit current (JSC) of 45 μA/cm2 and an open circuit potential (VOC) of 3.6 V at 25°C.
