摘要：

The transport properties of gel-type ionic conducting membranes consisting of poly(methylmethacrylate) (PMMA), polyethylene oxide (PEO), LiX (X = ClO4, BF4, CF3SO3) and dimethyl phthalate (DMP) are studied. The polymer films are characterized by FTIR and impedance spectroscopic studies. At room temperature, the highest conductivity, viz., 0.64 x 10(-4) S cm(-1), is obtained for a film of PMMA, PEO, LiBF4 and DMP. Hybrid polymer electrolytes based on PMMA-PEO appear very promising for lithium battery applications. (C) 2001 Elsevier Science B.V. All rights reserved.
