ION CONDUCTORS

摘要

An ion conducting polymeric material characterised in that it comprises a mixture of at least three components (a), (b) and (c): (a) one or more structural materials, (b) one or more low mass plasticizers, and (c) one or more amorphous ion-solvating polymers and optionally containing (d) one or more ionic salts. Preferably the structural material is poly(ethylene oxide) and the ion-solvating polymer is an oxymethylene linked polyethylene glycol having a repeat sequence [(CH2CH2O)aCH2O] where a has an average value of 4 to 15.
