Abstract
The plasticized polymer electrolytes composed of poly(methyl methacrylate-c o-li maleate), lithium perchlorate, and ethylene carbonate as a plasticizer , were newly prepared. The ion conductivities of the plasticized polymer el ectrolytes based on the poly(methyl methacrylate-co-Li maleate) were found to be dependent on the ion content of the ionomer, poly(methyl methacrylate -co-li maleate), in the polymer electrolyte, and the polymer electrolyte ba sed on the ionomer with 8.5 mol% ion content showed the maximum ion conduct ivity. The interfacial resistance at the polymer electrolyte/lithium interf ace and the cationic transference number were also investigated as a functi on of the ion content of the ionomer in the polymer electrolyte. The interf acial resistances as well as the cationic transference numbers of the polym er electrolytes were found to be also dependent on the ion content of the i onomer in the polymer electrolyte. Ion aggregations in the ionomer seemed t o significantly influence the electrochemical behavior of the polymer elect rolytes based on the ionomer. (C) 2001 Elsevier Science B.V. All rights res erved.
