A series of polyacrylonitrile-sulfolane-CuX2 (PAN-TMS-CuX2, where X = Cl, B
r, CF3SO3) polymer electrolytes, of thickness between 0.03 and 0.07 cm, wer
e 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 varia
tion of the conductivity for all the systems studied was of the Arrhenius t
ype. Exchange current density at the Cu I electrolyte interface, determined
from the Tafel plot, was of the order of milliampere (mA). Cyclic voltamme
try showed the irreversible character of the copper plating-stripping proce
