Abstract :
Polymer electrolytes were prepared from polyethylene glycol (PEG)-lithium perchlorate complexes and characterized at a stainless steel electrode using a variety of electrochemical techniques. The charge transfer process was affected by the oxide film on the stainless steel electrode surface in the early stages of redox processes. The polymer electrolytes showed a transference number of 0.2 for Li+ . The conductivity of the PEG-10000 electrolyte has been determined to be 4.7×10-5 S/cm. This rather high value is attributed to tile anionic end groups increasing the polarity of the matrix
