Polymer electrolytes based on polyacrylonitrile (PAN) with various pla
sticizers have been synthesized. Their electrical conductivities deter
mined by AC impedance spectra are higher than 1 x 10(-3) S . cm(-1) at
room temperature. IR and Raman spectra gave evidence of the interacti
ons among PAN, plasticizer and lithium salt.
