“…The changes in wavenumber revealed the complexes between alginate and LiNO 3 via weak van der Waals attraction of dipole-dipole forces [20] and this would lead to affect the ionic conduction in BEs system. Besides, the Li + from LiNO 3 function as electrophile positive ion in order to interact with polar group of alginate (Li + K − O) [21]. On the other hand, the absorption peak for COO − symmetric stretching shifted to lower wavenumber from 1409 to 1400 cm −1 which confirms that the migration of Li + to the coordinating site (oxygen) of COO − via electrostatic interaction in order to form (Li + K − OOC) [22].…”

In this present work, the conduction properties of biopolymer electrolytes (BEs) based alginate incorporation with LiNO 3 was studied. FTIR analysis showed there is complexation occurred when incorporation with LiNO 3 via COO − group of alginate. The interaction between alginate and LiNO 3 shown an improvement in ionic conductivity of BEs where was increased from 3.24×10 -7 S cm −1 for un-doped sample and achieved optimum value at 1.14×10 -4 S cm −1 for sample containing with 15 wt. % LiNO 3 . The prepared samples shown that it has thermally assisted when the temperature is increased and shown Arrhenius behavior. Deconvolution approached revealed that the present ionic conduction of BEs influenced by ionic mobility and diffusion coefficient.

A new polymer electrolyte based on the biopolymer Agar-Agar doped with ammonium thiocyanate (NH 4 SCN) has been prepared and characterized by FTIR analysis, X-ray diffraction measurements, AC impedance spectroscopy, transference number measurements, and DSC analysis. The Fourier transform infrared analysis confirms the complex formation between agar and NH 4 SCN. The amorphous nature of the polymer electrolyte has been revealed from X-ray diffraction analysis. The highest ionic conductivity has been observed for the sample of composition 1:1 between Agar and NH 4 SCN. As a function of temperature, the ionic conductivity of this sample exhibits Arrhenius behavior increasing from 1.03 3 10 23 S cm 21 at ambient temperature to 3.16 3 10 23 S cm 21 at 343 K. The transference number has been estimated by the dc polarization method, and it has been proven that the conducting species are predominantly cations. Using the highest conductivity polymer electrolyte, solid state electrochemical cell has been fabricated and cell parameters are reported.

“…Biodegradable natural polymers are used to prepare polymer electrolyte films for several applications. In the earlier reports reveals that the biopolymer based solid polymer electrolytes such as Pectin [9], Sodium alginate [10], agar-agar [2], cellulose acetate [11] and chitosan [12] are reported. The green polymer Pectin is used in this work which is a polysaccharide natural polymer, great abundance, acts as a cementing material in the cell walls of all plant tissues and so on [13].…”

In the present study, Pectin based Lithium sulfate added biopolymer electrolytes have been prepared by using Solution casting technique. Surface morphology of the prepared sample is investigated by Scanning Electron microscopy and crystalline nature is investigated by X-ray Diffraction. These films have a smooth surface and amorphous nature with good transparency. The Pectin is biopolymer which is ecofriendly and great abundance in earth. The maximum ionic conductivity value is obtained for 85Pectin:15Li2SO4 system. The change in ionic conductivity related to concentration of salt is also analyzed. The dielectric properties of the Pectin based system are also discussed.
