Resumen:
Solid polymer electrolytes of polyethylene oxide (PEO) embedded with
LiCF3SO3 was prepared and subjected to X-ray irradiation of different
dosages (1.5 to 6 Gy). Ionic conductivity and dielectric studies were
made over a frequency range of 100 Hz to 490 KHz. A little increase in
ionic conductivity was noted for the sample irradiated for 1.5 Gy and
the equivalent circuit remained unaltered for irradiated samples.
Remarkable increase in dielectric constant was found for the irradiated
samples. It was found that irradiation improved the dissolution of
lithium salt and increased the polymer/Lithium interaction and thus
improved the polarizability of the electrolyte. The frequency of hopping
and liberation of free lithium ions were found altered by irradiation
and hence the given dosage was found to have an optimum value in concern
with the ionic conductivity of the electrolyte.
