AbstractIn this study, a polypropylene (PP) mesh was used to prepare proton- and Li+ conducting composite membranes for fuel cells and lithium rechargeable batteries, respectively. For the preparation of Li+ conducting membrane, polypropylene mesh was first immersed in an electrolyte solution, which was composed of LiBF4 and ethylene carbonate. Then the swollen membrane was immersed in an acetone solution of polyethylene glycol diacrylate (PEGDA), polyvinylidenefluoride-co-hexafluoro-propylene and photoinitiator. Finally, PP fabric was taken out from the solution and exposed to UV irradiation. Furthermore, proton conducting membranes were prepared by immersing the PP mesh into a mixture of vinyl phosphonic acid, PEGDA and photoinitiator. Afterwards, samples were cured under UV light. PP-reinforced membranes designed for fuel cell applications exhibited a room temperature conductivity of 3.3×10-3 mS/cm, while UV-cured electrolyte for Li batteries showed ionic conductivities in the range of 1.61×10-3–5.4×10-3 S/cm with respect to temperature. In addition, for lithium-doped composite polymer electrolyte (CPE), the electrochemical stability window was negligible below 4.75 V vs. Li/Li+. It is concluded that lithium-doped CPE has suitable electrochemical stability to allow the use of high-voltage electrode couples.

Lithium Tetrafluoroborate

Polyacrylonitrile (PAN) based polymer electrolytes composed of PAN, lithium tetrafluoroborate (LiBF4), ethylene carbonate (EC) and dimethyl phthalate (DMP) were prepared by solution casting technique. The variation of conductivity with LiBF4 concentrations of the prepared films has been studied using AC impedance spectroscopy. The conductivity of the films is charge concentration dependent and the highest room temperature conductivity of 1.08 ×10-2 S cm-1 is achieved for the film with optimum composition. The thermal activated conductivity of the films obeys Arrhenius rule in the temperature range from 303 K to 353 K. The electrochemical stability of the PAN-based films has been investigated using linear sweep voltammetry (LSV) with three electrodes system. The films were found to be electrochemically stable up to 4.4 V. The reversibility of the lithium ions conduction in the polymer electrolyte films have been studied using cyclic voltammetry (CV).

Multi Walled Carbon Nanotube

The present investigation deals with the preparation of multi-walled carbon nanotube (MWCNT)-doped plasticized polymer electrolyte. The nanocomposite has been prepared using solution casting method. Complex impedance spectroscopy study revealed the utmost room temperature conductivity of 5.6 × 10−4 S/cm when optimized plasticized polymer electrolyte (poly(ethyl methacrylate)+30% sodium iodide+60% ethylene carbonate) was doped with 7% MWCNT. Temperature dependence of conductivity showed Arrhenius behavior. The surface morphology and crystalline–amorphous deviation of the composite was observed using scanning electron microscope. Perfect complexation of various components of the composite was confirmed from Fourier-transform infrared spectroscopy and X-ray diffraction (XRD) data. The transference number measurement was done to calculate the proportionate amount of ionic and electronic conductivity. A dye sensitized solar cell has been fabricated using maximum ionic conductivity of solid polymer electrolyte and its electrical parameters measured at 1 sun condition.
