ABSTRACT
A perspective on the problem of ion conduction in polymer electrolytes, focusing on the properties of polymer that favor ion transport is provided. Contemporary issues in polymer electrolytes are briefly discussed next. This is followed by an account of of two fundamental experimental skills: electrical conductivity and positron annihilation. Following up on one 244 of the contemporary issues, recent innovations aimed at enhancing ion conduction are discussed with the aid of most recent work. A fundamental model of ion conduction in polymers based on free volume concept is briefly outlined. Future directions include (1) use of fragile polymers to decouple the ionic conductivity relaxation from segmental relaxation; (2) use of diblock and triblockcopolymers, and (3) polymerization of ionic liquids. Future years would hopefully witness the development and use of new polymer electrolytes andexploration of mechanisms of ion conduction in them.
