摘要 | Rechargeable aqueous zinc-ion batteries (ZIBs) are receiving increased attention because of their high safety and low cost. However, their practical application is plagued by their low energy density as a result of low output voltage and a narrow voltage window of aqueous electrolytes. Here, we explored a ZIB with a wider potential window using bication (1 M Al(CF3SO3)(3)/1 M Zn(CF3SO3)(2)) as the electrolyte and alpha-MnO2 as the cathode, obtaining a discharge voltage of 1.7 V, similar to 0.3 V higher than the value reported earlier. The resultant cell delivers a record high energy density of 448 W h kg(-1) (based on MnO2 mass) and retains 100% capacity over 1000 cycles. The ion-storage mechanism and the role of Al3+ in enlarging the output voltage were elucidated. This research indicates the important role of using bications in improving the electrochemical performance of aqueous ZIBs, opening a new way to increase the energy density of aqueous energy storage devices. |
