摘要
A series of polyacrylonitrile-sulfolane-CuX2 (PAN-TMS-CuX2, where X = Cl, Br, CF3SO3) polymer electrolytes, of thickness between 0.03 and 0.07 cm, were prepared by means of the solution cast technique. The solvent content was as high as 60-70 wt.%. Conductivities of the foils obtained from impedance measurements were of the order of 10(-3) Ohm (-1) cm(-1) Temperature variation of the conductivity for all the systems studied was of the Arrhenius type. Exchange current density at the Cu I electrolyte interface, determined from the Tafel plot, was of the order of milliampere (mA). Cyclic voltammetry showed the irreversible character of the copper plating-stripping process. (C) 2001 Elsevier Science B.V. All rights reserved.
