%X Effect of polar acrylamide (AM) group on the conductivity of Li+-conducting polymers is studied, in which the conductivity data are analyzed by Vogel-Tammann-Fulcher(VTF) equation and interpreted by the configurational entropy model. The linear VTF polts revealthat there is a close correlation between ionic conductivity and segmental motion of the polymers. Polar AM groups may enhance the dissociation degree of the salt species and lower the activation energy of exchange process of the Li+-O bonds during ionic transport , but also increase the rigidity of polymer segments. As a result, ionic conductivity of the copolymers is promoted as long as AM content is below ca. 15 wt%.
