| description | <p dir="ltr">The potential application of rechargeable multivalent ion batteries in portable devices and renewable energy grid integration have gained substantial research interest in aqueous Zn-ion batteries (ZIBs). Compared to Li-based batteries, ZIBs offer lower costs, higher energy density, and safety that make them more attractive for energy storage in grid integration applications. Currently, more research is required to find a suitable cathode material for ZIBs with high capacity and structural stability during charge/discharge cycling. Vanadium phosphate (VOP) compounds as cathode material for ZIBs have been of particular interest, owing to vanadium’s diverse oxidation states. In this present work, two VOP compounds, [H0.<sub>6</sub>(VO)<sub>3</sub>(PO<sub>4</sub>)<sub>3</sub>(H2O)<sub>3</sub>].4H<sub>2</sub>O and VOPO<sub>4</sub>.2H<sub>2</sub>O, were synthesized from phosphoric acid and different sources of vanadium via a simple hydrothermal method. Various characterization techniques were carried out, revealing the layered structure of both products and high purity of [H0.<sub>6</sub>(VO)<sub>3</sub>(PO<sub>4</sub>)<sub>3</sub>(H<sub>2</sub>O)<sub>3</sub>].4H<sub>2</sub>O. Zn/VOP batteries were prepared using Zn metal as counter and reference electrode and 3 M ZnSO<sub>4</sub>.7H<sub>2</sub>O as electrolyte. Electrochemical tests were conducted to evaluate the cycling performance of VOPs as cathode material for aqueous Zn-ion batteries. Based on the results, both compounds have shown highly reversible Zn-ion intercalation and deintercalation. VOPO<sub>4</sub>.2H<sub>2</sub>O achieved a higher specific capacity of up to 85 mAh/g during discharging, as opposed to 65 mAh/g for the hydrated VOP complex. However, [H0.<sub>6</sub>(VO)<sub>3</sub>(PO<sub>4</sub>)<sub>3</sub>(H<sub>2</sub>O)<sub>3</sub>].4H<sub>2</sub>O is more stable with higher reproducibility than VOPO<sub>4</sub>.2H<sub>2</sub>O during cycling. Nevertheless, more research is still required to enhance the specific capacity and improve the cycling performance of VOP-based cathodes for their prospective use in aqueous ZIBs.</p><h2>Other Information</h2><p dir="ltr">Published in: Frontiers in Materials<br>License: <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank">https://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.3389/fmats.2021.645915" target="_blank">https://dx.doi.org/10.3389/fmats.2021.645915</a></p> |
