“…The Fig. 1a indicates that the undoped polymer CA shows crystalline peaks at 2h = 9°, 13°, 18°, 23°and 27°, which correlates with the literature [9,10]. The XRD patterns also indicates that the broadness of peak increases and its relative intensity decreases with increase of NH 4-SCN concentration, which reveals that as ion concentration in the electrolyte increases, both the fraction of amorphous phase and charge carriers increases simultaneously [22].…”

“…The biodegradable polymer CA doped lithium perchlorate (LiClO 4 ) has been studied for supercapacitors by Selvakumar et al [15]. Performance of CA membrane with lithium salts especially for lithium polymer cells have been studied by Ramesh et al [9,10]. However, until today not much effort has been taken by researchers to develop CA as a solid membrane with proton salts.…”

“…The CA has polar groups that possess lone pair electrons, which facilitates the ionic conduction. However, the high glass transition temperature, rigidity or high crystalline nature of CA hindered its applications [9,10], which can be overcome by adding inorganic salts to the CA. The gel polymer electrolyte CA has been used as a separator for various kinds of batteries, such as lead acid batteries and silver-zinc rechargeable batteries.…”

In this present work, the solution casting technique was utilized to develop the proton conducting solid biopolymer electrolyte by the complex formation of cellulose acetate (CA) with the ammonium thiocyanate (NH 4 SCN) salt. The crystalline nature and complex formation of CA with different concentrations of NH 4 SCN were investigated using X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopic techniques. The XRD analysis revealed that the amorphous natures of the CA complex were increased with increase of NH 4 SCN salt concentration, which leads to the higher ionic conductivity. The FTIR analysis confirmed the complex formation between CA and salt matrix. Differential scanning calorimetry (DSC) was used to predict the glass transition temperature (T g ) values, which reveals that the T g value increase with respect to the increase of NH 4 SCN concentration. The electrical conductivity was measured using AC impedance analyzer, which showed that the magnitude of ionic conductivity increases with an increase in salt concentration up to 50CA:50NH 4 SCN. The 50CA:50NH 4 SCN has maximum ionic conductivity value of 3.31 9 10 -3 S cm -1 . Transference number measurement was carried out to investigate the nature of the charge transport species in the polymer electrolyte. The proton battery was constructed with the highest conducting polymer electrolyte 50CA:50NH 4 SCN and its open circuit voltage with load were studied. Hence, the present investigation paves the way for the development of fuel cell and primary proton battery applications.

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.

Abstract:Since the realization that global sustainability depends on renewable sources of materials and energy, there has been an ever-increasing need to develop bio-based polymers that are able to replace petroleum-based polymers. Research in this field has shown strong potential in generating high-performance functionalized polymers from plant biomass. With the anticipated large-scale production of lignocellulosic biomass, lignin, cellulose and hemicellulosic polysaccharides will be abundantly available renewable feedstocks for biopolymers and biocomposites with physico-chemical properties that match or exceed those of petroleum-based compounds. This review examines the state of the art regarding advances and challenges in synthesis and applications of specialty polymers and composites derived from cellulose, hemicellulose and lignin, ending with a brief assessment of genetic modification as a route to tailor crop plants for specific applications.
