Polymer electrolytes. Problems, prospects, and promises
This paper reviews the evolution of polymer electrolytes from the conventional PEO-LiX salt complexes to the more conducting polyphosphazene and copolymers, gelled electrolytes etc. It also reviews the various chemical approaches including modifying PEO to synthesizing complicated polymer architecture. In addition, it discusses the effect of various lithium salts on the conductivity of PEO-based polymers. Charge/discharge and cycle life data of polymer cells containing oxide and chalcogenide cathodes and lithium (Li) anode will be reviewed. Finally, future research directions to improve the electrolyte properties will be presented.
