“…Alternative solid electrolyte materials, such as those based on polymers that can operate at ambient temperatures, could resolve these issues. However, compared to lithiumbased materials there have been relatively few studies of sodiumbased polymer electrolytes [13][14][15][16][17][18][19][20].…”

“…Both crystalline and amorphous phases are simultaneously present in these polymer electrolytes and only the amorphous phase is reported to be the high conducting phase [7], so different plasticizers were ",ddcd to these polymer electrolytes to increase the content of amorphous phase and hence conductivity value . The problem of mobility of both cations and anions can be avoided by using polyelectrolytes in which one of the ions (cation/anion) is attached to the polymer chain but the complex chemical processing involved alongwith still lower value of conductivity is not suitable for their use in different solid state ionic devices [10]. Liang in 1973 reported that when an inert insulating matrix like A120~ is ~lded to an ion conductor like LiI, the conductivity increases by a large amount these electrolytes are known as composite electrolyte or dispersed second phase electrolytes [11].…”

Abstract. The paper reports the synthesis of protonic polymer gel electrolytes containing different hydroxy benzoic acids (ortho-, meta-and para-) and aliphatic dicarboxylic acids. Gel electrolytes were prepared by adding polymethylmethacrylate (PMMA) in diffcrent weight ratios to the I M solution of above acids in a ternary solvent mixture of propylene carbonate (PC), cthylcne carbonate (EC) and dimethylformamide (DMF) in equal volume ratio. The conductivity of these gel electrolytes has been found to depend upon the amount of PMMA ~cd to the system. A "Breathing Polymeric Chain Model" has been proposed to explain the variation of conductivity with PMMA concentration in these gel electrolytes.

“…The resulting composites are two-dimensional nanostructures of silicate layers alternating with cations and intercalated compound as verified by powder x-ray diffraction (XRD). of the conductivity in many polyelectrolytes (34). MEEP was chosen because its oligoether side chains solvate Na + and the high flexibility of the backbone (2).…”

Poly(bis-methoxyethoxyethoxy phosphazene)(MEEP) and cryptand[2.2.2] (crypt) have been intercalated separately into sodium exchanged montmorillonite (Na-mont), and impedance spectroscopy indicates that ionic conductivities of the resulting nanocomposites (log σ = -7.6 (Ω•cm) -1 for MEEP/Na-mont and log σ = -8.1 (Ω•cm) -1 at 100°C) are enhanced by several orders of magnitude over the parent Na-mont. Intercalation is demonstrated by powder x-ray diffraction and FTIR spectroscopy. 23 Na and 29 Si MAS NMR spectra give evidence that the interlayer Na + are solvated by the intercalated ethers. FTIR spectroscopy, 13 C NMR spectroscopy and 1 H NMR spectroscopy indicate that cryptand intercalates preferentially to MEEP when a mixture of the two is stirred with Na-Mont.Solid state electrolytes are the subject of increasing interest because of their potential in technical applications and for fundamental questions regarding conduction mechanism. Our group, as well as others, has been heavily involved in the exploration of polymer ion conducting systems such as poly(ethylene oxide) (PEO) / lithium triflate (LiS0 3 CF 3 ) complexes (7), poly(bis-methoxyethoxyethoxy phosphazene) (MEEP) / LiS0 3 CF 3 complexes (2), and poly(oligoether aluminosilicate) polyefectrolytes (3). The focus of study has shifted as understanding of structure of polymer electrolytes and mechanism of ion transport has developed. The topic of this paper, nanostructured clay intercalation compounds, represents a new direction in solid electrolytes (4-6). Polymer-Salt Complexes and PolyelectrolytesResearch on solvent-free polymer-salt complexes accelerated after the pioneering studies of PEO-alkali metal salt complexes conducted by Armand (7,5) and Wright (9-11).
