“…Furthermore, environmental pollution and energy shortages are becoming exacerbated (Cheng C. et al, 2020 ; Chuanchang et al, 2020 ; Huang et al, 2020a ; Yang et al, 2020 ). Therefore, new energy development technologies have received widespread attention (Huang et al, 2020b ; Wang D. et al, 2020 ; Liu et al, 2021 ; Nie et al, 2021 ). However, new resources, such as solar and tidal energies, cannot provide a continuous source of energy.…”

In this study, a SnO2-carbon nanotube (SnO2-CNT) composite as a catalyst for vanadium redox flow battery (VRFB) was prepared using a sol-gel method. The effects of this composite on the electrochemical performance of VO2+/VO2+, and on the V2+/V3+ redox reactions and VRFB performance were investigated. The SnO2-CNT composite has better catalytic activity than pure SnO2 and CNT due to the synergistic catalysis of SnO2 and the CNT. SnO2 mainly provides the catalytic active sites and the CNTs mainly provide the three-dimensional structure and high electrical conductivity. Therefore, the SnO2-CNT composite has a larger specific surface area and an excellent synergistic catalytic performance. For cell performance, it was found that the SnO2-CNT cell shows a greater discharge capacity and energy efficiency. In particular, at 150 mA cm−2, the discharge capacity of the SnO2-CNT cell is 28.6 mAh higher than that of the pristine cell. The energy efficiency of the modified cell (7%) is 7.2% higher than that of the pristine cell (62.8%). This study shows that the SnO2-CNT is an efficient and promising catalyst for VRFB.

“…The addition of MnSO 4 to electrolytes can inhibit this side reaction to a certain extent, because additional Mn 2+ influences the balance between Mn 2+ dissolution and reoxidation [16]. To further improve the cycling performance of MnO 2 , a common strategy is surface coating by conductive carbon materials or polymer materials, which cannot only enhance the electrical conductivity of MnO 2 and ease volume changes, but also prevent Mn dissolution [17]. However, the improvement of cycle life is limited due to the poor reversibility of the MnO 2 /Mn 2+ redox reaction [18].…”

The Zn/MnO2 battery is a promising energy storage system, owing to its high energy density and low cost, but due to the dissolution of the cathode material, its cycle life is limited, which hinders its further development. Therefore, we introduced agar as a microskin for a MnO2 electrode to improve its cycle life and optimize other electrochemical properties. The results showed that the agar-coating layer improved the wettability of the electrode material, thereby promoting the diffusion rate of Zn2+ and reducing the interface impedance of the MnO2 electrode material. Therefore, the Zn/MnO2 battery exhibited outstanding rate performance. In addition, the agar-coating layer promoted the reversibility of the MnO2/Mn2+ reaction and acted as a colloidal physical barrier to prevent the dissolution of Mn2+, so that the Zn/MnO2 battery had a high specific capacity and exhibited excellent cycle stability.
