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.

“…Moreover, the same author has explored the effect of MgCl 2 on the various properties of pectin electrolytes. This finding indicates that the composition of 30 (M.wt%) pectin: 70 (M.wt%) MgCl 2 shows the highest Mg-conductivity of 1.14 × 10 −3 Scm −1 with the transference number of 0.30 and exhibits the window stability of 2.05 V. The primary device was conducted using Mg-metal, MnO 2 /graphite, and above highest complex as an anode, cathode, and electrolyte, respectively, and demonstrates the OCP of 2.16 V. The various alkali metal salt incorporated pectin-based electrolytes [39][40][41][42][43] and their ionic conductivity values are bar graphically represented in Figure 3. Based on the discussion, most of the pectin-based ion conducting system exhibits the ionic conductivity range from 10 −3 to 10 −4 Scm −1 .…”

Polysaccharide-based natural polymer electrolyte membranes have had tremendous consideration for the various energy storage operations including wearable electronic and hybrid vehicle industries, due to their unique and predominant qualities. Furthermore, they have fascinating oxygen functionality results of a higher flexible nature and help to form easier coordination of metal ions thus improving the conducting profiles of polymer electrolytes. Mixed operations of the various alkali and alkaline metal–salt-incorporated biopolymer electrolytes based on different polysaccharide materials and their charge transportation mechanisms are detailly explained in the review. Furthermore, recent developments in polysaccharide electrolyte separators and their important electrochemical findings are discussed and highlighted. Notably, the characteristics and ion-conducting mechanisms of different biopolymer electrolytes are reviewed in depth here. Finally, the overall conclusion and mandatory conditions that are required to implement biopolymer electrolytes as a potential candidate for the next generation of clean/green flexible bio-energy devices with enhanced safety; several future perspectives are also discussed and suggested.

“…It was also stated that the increase in temperature up to 80°C promoted an increase in the ionic conductivity to 3.32 Â 10 -4 S cm À 1 [273]. Pectin-based membranes with different salts such as LiClO 4 , KCl, LiClO 4 -Ir(III) and KCl-Ir(III) contents are prepared and studied by Leones et al [274]. The most conductive sample of Pectin and KCl exhibits the ionic conductivity of 1.45 Â 10 À 3 S cm À 1 and 6.31 Â 10 À 3 S cm À 1 at 25°C and 90°C, respectively.…”

a b s t r a c tPhotovoltaic technologies represent one of the leading research areas of solar energy which is one of the most powerful renewable alternatives of fossil fuels. In a common photovoltaic application the batteries play a key role in storage of energy generated by solar panels. Although it will take time for dye sensitized solar cells (DSSCs) and batteries based on biopolymer electrolytes to take their places in the market, laboratory studies prove that they have a lot to offer. Most efficient DSSCs and batteries available in market are based on liquid electrolytes. The advantages of liquid electrolytes are having high conductivity and good electrode-electrolyte interface whereas, disadvantages like corrosion and evaporation limit their future sustainability. Biopolymer electrolytes are proposed as novel alternatives which may overcome the problems stated above. In this review, we focus on fabrication, working principle as well as up to date status of DSSCs and batteries using biopolymer electrolytes. The effects of structural and electrical properties of biopolymer based electrolytes on the solar energy conversion efficiencies of DSSCs and their compatibility with lithium or other salts in battery applications are summarized. Biopolymer electrolyte based DSSCs are categorized on the basis of types of additives and recent outcomes of author's laboratory studies on biopolymer electrolyte based DSSCs and batteries are also presented.
