“…In a similar manner, the decrease in crystallinity index of the cellulose based films may be attributed to disturbance due to the existence of graphene platelets [36]. Besides, graphene particles may prevent the polymer chain reorganization, which causes reduction in polymer crystallinity [37].…”

“…The increase in conductivity with temperature has been explained in terms of the free volume model. 15 When the temperature increase, the polymer can expand easily and then produce free volume (i.e., when the temperature increase, the free volume increase). 15 When the free volume increased the mobility of ions increased leading to increase in the conductivity.…”

When the temperature increased the vibrational energy of a segment is appropriate to push against the hydrostatic pressure imposed by its neighboring atoms which make a small amount of space a rounding its own volume in which vibrational motion can occur.…”

In the present work, polymer electrolyte (PE) film consisting of poly(vinyl alcohol) (PVA) with magnesium bromide (MgBr 2 ) as electrolytic salt, tetraethylene glycol dimethyl ether (TEGDME) as plasticizer and Li 2 O at different concentration (0.02, 0.04, 0.06 wt.%) as the filler has been prepared by solution casting technique. The polymeric film was flexible and self-standing with proper mechanical strength and studied for application in a solid-state rechargeable magnesium battery. The interactions between the filler and PVA chains are studied by X-ray and thermogravometric analyses. The conductivity increased with addition of filler reached to ∼ 10 −5 S · cm −1 at 0.04 wt.% Li 2 O. The frequency dependence of ac conductivity obeys Jonscher power law. The estimated value of Mg +2 ion transference number is found to be 0.7 for high conducting film. A solid state battery based on the optimum polymer electrolyte with a configuration Mg PE V 2 O 5 has exhibited an open circuit voltage of 1.5 V. Also this battery has exhibited a discharge capacity ≈ 6.11 mA h. The discharge characteristics are found to be satisfactory as a laboratory cell.

“…The low ionic conductivity of polymer electrolytes at ambient temperatures has been a major drawback for developing practical rechargeable batteries based on them. Recently, composite polymer electrolytes (CPEs) made of an inorganic component such as titanium dioxide (TiO 2 ), silicon dioxide (SiO 2 ), cerium oxide (CeO 2 ), aluminum oxide (Al 2 O 3 ), and a conventional salt-in-polymer electrolyte have received considerable attention due to suppression of polymer crystallization, 3 enhancement of the mechanical properties, 4 conductivity, 5 and cation transference numbers. 6 Many types of solid polymer electrolytes (SPEs) have been proposed based on organic polymer matrices that dissolved inorganic salts, especially alkali metal salts.…”

Composite polymer electrolyte (CPE) materials are very attractive for components of batteries and optoelectronic devices. Polyethylene glycol-magnesium nitrate polymer electrolytes and their composites were prepared by using addition of different weight percentage of titanium dioxide (TiO 2 ) and cerium oxide ceramic fillers. Several experimental techniques, such as composition-dependence conductivity, temperature-dependence conductivity, and transport number measurements, have been employed to characterize these CPEs. The magnitude of conductivity increased with increase in the concentration of the ceramic fillers and temperature. The highest ionic conductivity achieved was 1.06 Â 10 À4 S/cm for the sample prepared with 10 wt% of TiO 2 at room temperature. The charge transport in the present CPEs was obtained using Wagner's polarization technique, which demonstrated that the charge transport was mainly due to ions. Using these polymer electrolytes, solid-state electrochemical cells were fabricated and their discharge profiles were studied under a constant load of 100 k.
