Solid polymer electrolyte (SPEs) develop from carboxymethyl cellulose (CMC),
ammonium carbonate (AC), and plasticized with the ethylene carbonate (EC) is studied
for its electrical properties via electrical impedance spectroscopy (EIS) and its
structural properties via X-Ray diffraction (XRD) and Fourier Transforms Infrared
(FTIR). The conductivity of the system without the plasticizer is 1.39 x 10 -7 Scm -1 . The
introduction of EC as the plasticizer in the system give an increments of the
conductivity value. The conductivity improves from 1.39 x 10 -7 Scm -1 to 3.19 x 10 -4
Scm -1 . As the concentration of EC increase in the system, the number of H + ion
dissociate in the system also increase. Structural analysis using XRD display that the
system is amorphous in nature. The FTIR spectrum show that there a new peak
appeared as the concentration of EC increase.
