Abstract

Exploring wide voltage window materials is not only an available measure to enhance the energy density of hybrid supercapacitor (HSCs), but also avoids the dynamic mismatch caused by different energy storage mechanisms of two electrodes in assembled symmetrical HSC. However, there are few reports about the wide potential window materials except Bi2O3 and VO2. Therefore, the MnF2 synthesized by solvothermal reaction was served as the electrode for HSC. The MnF2 exhibited electrochemical activity in alkaline solution in three-electrode system, especially with a wide potential window from −0.8 to + 0.5 V in 2 mol·L−1 NaOH. Furthermore, the assembled MnF2//MnF2 symmetrical HSC had a potential window of 1.5 V, and it exhibited outstanding long-cycle capability. Meanwhile, when MnF2 was taken as the negative and positive respectively, the potential windows of asymmetric devices CoMoO4//MnF2 and MnF2//Activated Carbon (AC) could reach 1.3 and 1.45 V, respectively, showing excellent cycle stability. This work shows that MnF2 material has great research value in HSC, and provides a new research direction for developing high-performance devices.
