Electrochemical Performance of Graphene-Modulated Sulfur Composite Cathodes Using LiBH<sub>4</sub> Electrolyte for All-Solid-State Li-S Battery
All-solid-state Li-S batteries (use of solid electrolyte LiBH<sub>4</sub>) were prepared using cathodes of a homogeneous mixture of graphene oxide (GO) and reduced graphene oxide (rGO) with sulfur (S) and solid electrolyte lithium borohydride (LiBH<sub>4</sub>), and their ele...

Résumé: | All-solid-state Li-S batteries (use of solid electrolyte LiBH<sub>4</sub>) were prepared using cathodes of a homogeneous mixture of graphene oxide (GO) and reduced graphene oxide (rGO) with sulfur (S) and solid electrolyte lithium borohydride (LiBH<sub>4</sub>), and their electrochemical performance was reported. The use of LiBH<sub>4</sub> and its compatibility with Li metal permits the utilization of Li anode that improves the vitality of composite electrodes. The GO-S and rGO-S nanocomposites with different proportions have been synthesized. Their structural and morphological characterizations were performed by X-ray diffraction (XRD) and scanning electron microscopy (SEM), and the results are presented. The electrochemical performance was tested by galvanostatic charge-discharge measurements at a 0.1 C-rate. The results presented here demonstrate the successful implementation of GO-S composites in an all-solid-state battery. |
