The increasing energy demand on available global lithium resources has created concerns on development of new and advanced sustainable energy sources. Sodium-based batteries have emerged as promising substitutions to Li-based batteries. We describe here sodium trifluoromethanesulfonate (NaCF3SO3) electrolyte system based on tetraethylene glycol dimethyl ether (tetraglyme). The ionic conductivity of...
Nanocomposite biopolymer electrolyte was prepared by solution-casting technique. Carboxymethyl cellulose from kenaf bast fibre, ammonium acetate, (1-butyl)trimethyl ammonium bis(trifluoromethylsulfonyl)imide ionic liquid and silica nanofiller was used to prepare the biopolymer electrolyte samples. The films were characterized by Fourier transform infrared spectroscopy, electrochemical impedance spectroscopy,...
In the present work, free standing films of methyl methacrylate and ethyl methacrylate complexed with different weight ratios of lithium iodide salt were successfully prepared via solution casting technique. Fourier transform infrared spectroscopy showed that the interaction between lithium ion and oxygen atoms occurred at carbonyl and ether group of the host copolymer. The incorporation of 20 wt%...
Biosourced carboxymethyl cellulose polymer electrolytes have been studied for potential application in electrochemical devices. The carboxymethyl cellulose was obtained by reacting cellulose derived from kenaf fibre with monochloroacetic acid. Films of the biosourced polymer electrolytes were prepared by solution-casting technique using ammonium acetate salt and (1-butyl)trimethyl ammonium bis(trifluoromethylsulfonyl)imide...
Novel biopolymer electrolytes based on carboxymethyl kappa-carrageenan (CMҡ-carrageenan) and ionic liquid 1-butyl-3-methylimidazolium chloride ([Bmim]Cl) have been successfully developed. Strong coordination and hydrogen bonding interaction of [Bmim]Cl with the biopolymer were detected by Fourier transform infrared (FTIR) spectroscopy. The efficient function of [Bmim]Cl as the charge carrier in the...
A new type of solid polymer electrolyte based on iota (ɩ)-carrageenan derivative has been investigated. ɩ-Carrageenan was reacted with monochloroacetic acid to produce carboxymethyl ɩ-carrageenan. The produced powders were characterized by 1 H nuclear magnetic resonance and attenuated total reflection Fourier transform infrared spectroscopy to confirm the substitution of targeted...
This paper reviews the use of solid polymeric electrolyte (SPE) and gel polymeric electrolyte (GPE) in photoelectrochemical cell (PEC) and dye-sensitized solar cell (DSSC).
