“…These characteristics make SPEs suitable candidates to be employed in a variety of energy storage devices such as computing laptops, cellular phones, electrochromic display devices, fuel cells, sensors, and smart credit cards [3,4]. Nowadays, the host polymers most commonly used by the researchers in the PEs are poly(vinyl alcohol) (PVA) [1][2][3][4][5][6][7], chitosan (CS) [8][9][10][11][12], methylcellulose (MC) [13][14][15], polyethylene oxide (PEO) [16][17][18], phosphomolybdic acid (PMA) [19], Nafion membranes [20], and sulfonated hydrocarbon [21].…”

In this study, porous cationic hydrogen (H+) conducting polymer blend electrolytes with an amorphous structure were prepared using a casting technique. Poly(vinyl alcohol) (PVA), chitosan (CS), and NH4SCN were used as raw materials. The peak broadening and drop in intensity of the X-ray diffraction (XRD) pattern of the electrolyte systems established the growth of the amorphous phase. The porous structure is associated with the amorphous nature, which was visualized through the field-emission scanning electron microscope (FESEM) images. The enhancement of DC ionic conductivity with increasing salt content was observed up to 40 wt.% of the added salt. The dielectric and electric modulus results were helpful in understanding the ionic conductivity behavior. The transfer number measurement (TNM) technique was used to determine the ion (tion) and electron (telec) transference numbers. The high electrochemical stability up to 2.25 V was recorded using the linear sweep voltammetry (LSV) technique.

“…These electrolytes really refer solvent-free PVA/salt complexes. Many research investigations have been dedicated to develop proton conducting [ 11 , 12 , 13 , 14 , 15 , 16 ], Mg 2+ conducting [17] , Cu 2+ conducting [18] and Li + ion conducting [ 10 , 19 , 20 , 21 ] and Ag 2+ [22] ion conducting electrolytes using PVA as host polymer. The electrolytes exhibit conductivity in the range of 10 −7 to 10 −3 S cm -1 at ambient temperature and are listed in Table 1 .…”

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.

Solid electrolyte at different composition of 50% PVA + 50 % PVP + x% NaH2PO2 are prepared using solution casting techniques. The prepared materials of polymer matrices are characterized through several techniques such as XRD, FTIR spectroscopy. The electrical conductivity of the sample is determined through measured impedance data at different frequencies and different temperatures. The electrical conductivity is calculated in the order of 10-8 Scm-1 . The water uptakencabability is also analysed. Proton conductivity is also analysed for vatious atmospheric condition.
