Conductivity and Dielectric Studies of Lithium Trifluoromethanesulfonate Doped Polyethylene Oxide-Graphene Oxide Blend Based Electrolytes
Abstract
<jats:p>Series of polymer blend consisting of polyethylene oxide (PEO) and graphene oxide (GO) as co-host polymer were prepared using solution cast method. The most amorphous PEO-GO blend was obtained using 90 wt.% of PEO and 10 wt.% of GO as recorded by X-ray diffraction (XRD). Fourier transform infrared spectroscopy (FTIR) analysis proved the interaction between PEO, GO, lithium trifluoromethanesulfonate (LiCF<jats:sub>3</jats:sub>SO<jats:sub>3</jats:sub>), and ethylene sulfite (ES). Incorporation of 25 wt.% LiCF<jats:sub>3</jats:sub>SO<jats:sub>3</jats:sub>into the PEO-GO blend increases the conductivity to<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mfenced separators="|"><mml:mrow><mml:mn>3.84</mml:mn><mml:mo>±</mml:mo><mml:mn>0.83</mml:mn></mml:mrow></mml:mfenced><mml:mo>×</mml:mo><mml:msup><mml:mrow><mml:mn>10</mml:mn></mml:mrow><mml:mrow><mml:mo>-</mml:mo><mml:mn>6</mml:mn></mml:mrow></mml:msup></mml:math> S cm<jats:sup>−1</jats:sup>. The conductivity starts to decrease when more than 25 wt.% salt is doped into the polymer blend. The addition of 1 wt.% ES into the polymer electrolyte has increased the conductivity to<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M2"><mml:mfenced separators="|"><mml:mrow><mml:mn>1.73</mml:mn><mml:mo>±</mml:mo><mml:mn>0.05</mml:mn></mml:mrow></mml:mfenced><mml:mo>×</mml:mo><mml:msup><mml:mrow><mml:mn>10</mml:mn></mml:mrow><mml:mrow><mml:mo>-</mml:mo><mml:mn>5</mml:mn></mml:mrow></mml:msup></mml:math> S cm<jats:sup>−1</jats:sup>.
