Chemical Preintercalation of H2V3O8-reduced Graphene Oxide Composites for Improved Na- and Li-ion Battery Cathodes
Abstract
<p>Due to a growing demand for sustainable electrical energy storage alternatives to Li-ion batteries (LIBs), Na-ion batteries (SIBs) are of great interest because of the abundance of Na<sup>+</sup>. By modifying layered H<sub>2</sub>V<sub>3</sub>O<sub>8</sub> by preintercalation and composite formation, improved electrochemical properties were obtained in LIBs. In analogy, a scalable soft chemistry synthesis is developed, to chemically presodiate H<sub>2</sub>V<sub>3</sub>O<sub>8</sub> for the first time, in addition to a composite formation reaction with reduced graphene oxide (rGO). Crystal structure and morphology of all compounds are determined and their electrochemical properties as cathode are evaluated with respect to both Na<sup>+</sup> and Li<sup>+</sup> intercalation. The combination of preintercalation and composite formation leads to excellent initial capacities of 96 mAh ⋅ g<sup>−1</sup> for SIBs and 371 mAh ⋅ g<sup>−1</sup> for LIBs (58 % and 48 % higher than unmodified H<sub>2</sub>V<sub>3</sub>O<sub>8</sub>) at a practical current density of 100 mA ⋅ g<sup>−1</sup>, demonstrating that H<sub>2</sub>V<sub>3</sub>O<sub>8</sub> is a promising cathode material for SIBs and LIBs.</p>
