ABSTRACT |
|
|
|
Lithium ion (Li+) conducting solid
polymer electrolytes have been prepared by solution casting method.
The prepared films were characterized using different techniques.
Fourier-transform infrared result revealed complexation of dopant
with the polymer through interaction of Li+ ion of LiCl with O-H and
C=O group of polyvinyl alcohol (PVA). Ultraviolet-visible spectra
show the change in optical properties such as optical energy band
gap and activation energy with doping level. Dielectric studies
revealed non-Debye nature of polymer electrolytes. Electrical
properties revealed that the maximum dc conductivity of 2.28 × 10−4
S/cm has been obtained for 15 wt% LiCl doped PVA at room
temperature. |
