The intensity of diffraction peaks decreases with increase
in salt concentration up to 2 M LiClO4. This shows a decrease
in crystallinity of the micro-porous polymer electrolyte.
It confirms the complete dissociation of LiClO4
and also the uptake of the electrolyte solution by the microporous
polymer membrane is somewhat higher than the
solid polymer film as shown in Fig. 1(a and b).
