Solid polymer electrolytes based on polyvinyl alcohol (PVA) and plasticized with ethylene glycol (EG) and/or phosphoric acid (H3PO4) have been developed to increase their proton conductivities. This electrolyte material has been characterized using various experimental techniques such as X-ray diffraction, infrared Fourier transform spectrometry and electrochemical impedance spectrometry. An optimum ionic conductivity value of the plasticized polymer electrolyte film has been achieved to be of the order of 10 −3 Scm −1 at relative humidity equal to 100% for 45 wt.% EG and 5 wt.% H3PO4. The minimum activation energy of this ternary complex is found to be 9 kJmol −1 for optimum conductivity condition. Using this ternary PVA-EG(45 wt.%)-H3PO4(5 wt.%) complex film as electrolyte, an "all solid state" Zn/MnO2 cell was fabricated and its discharge characteristics profile has been studied. In fact, the specific capacity and energy exceeding 200 Ahkg −1 and 250 Whkg −1 , respectively, have been observed experimentally in this cell.

“…The intensity of sharp peak gets decreased for salt doped polymer. The diminish in the intensity denotes that crystallinity reduced and become amorphous due to the doping of salt, which de nes the complexation of polymer and salt [24] . The doping of salt leads to the interaction of positive ions of the PVA hydroxyl group and weak interaction of negative ions leads to the amorphous nature of the sample [25] .…”

Electrochemical analysis of Silver ion conducting Gel polymer Electrolyte (Ag-GPE) was done with Linear sweep Voltammetry (LSV) and Cyclic Voltammetry (CV). The silver ion conducting GPE was prepared by solution casting technique with PVA as polymer, AgBF4 as salt and de-ionized water as solvent. The synthesized films were-characterized using XRD and-FTIR to study the structural and functional characteristics of GPE and confirmed the complexation between polymer and salt. The optical properties of the Ag-GPE sample was studied by UV-Vis spectrophotometer. The highest ionic conductivity, 1.28 × 10− 5 Scm-1 was observed for Ag-GPE sample (60:40 wt%) by AC impedance. Dielectric studies of Ag-GPE samples were done from AC impedance data. LSV used to analyze the electrochemical working voltage of the synthesized material, which is found to be 1.1V. CV studies were done for highest ion conducting GPE (60:40 wt%) by fabricating two different cells. The first cell SS/GPE/Ag showed good stability up to 25 cycles and the second cell Ag/GPE/Zn was analysed for the re-dox reaction of the cell which shows the electrochemical behaviour of battery and confirmed that, the synthesized material can be used for energy storage applications.

To date high ionic conducting polymer electrolytes are of great interest because of their potential applications in various electrochemical devices such as batteries, fuel cells, solar cells and super capacitors etc., as electrolytes. Ion conduction through polymer electrolytes can occur mostly in amorphous environment exists above their glass transition temperature (Tg). In order to improve ionic conductivity, many approaches such as addition of plasticizer, blending of polymers, nano composite have been employed. This paper reviews the influence of different plasticizers/additives on the ion transport mechanism of Poly(vinyl alcohol) (PVA)-LiClO4 polymer electrolytes since poly vinyl alcohol is a semi crystalline, synthetic biodegradable polymer and lithium perchlorate is one of the most moisture resistant lithium salts. This review also reveals the relation between dynamical disorder in polymer electrolyte with ionic conductivity.
