The harvesting energy from renewable sources are crucial for the green transition of technology, which aims to reduce the environmental impact that are essential for achieving a sustainable energy future. To provide electricity at all times irrespective of the presence of renewable energy sources, efficient energy storage devices are required. ESc (Esc) has the potential to store energy in the electrochemical form and deliver it in electric form when required. Symmetrical EScs are hindered by a low working window, low energy density (ED), and power density (PD). Here, the winning configuration of V12O26cathode and α-Fe2O3anode in divalent MgSO4electrolyte was carried out. V12O26exhibited a positive window (0 to 1 V) and α-Fe2O3negative window α-Fe2O3(0 to −1.2 V) complementary to achieve Mg2+ion-based aqueous asymmetric hybrid ESc (Mg-AHC) with an extended operating window 1.7 V in without disintegration of electrolyte. Mg-AHC showed fascinating ED (100.32 Wh/kg) in PD (1.65 kW/kg) and high initial retention capacitance (89 %) in 5000 cycles. Here, V12O26and α-Fe2O3were synthesised using simple and pragmatic procedures, as confirmed by XRD and XPS. The simple synthesis methods, the divalent neutral electrolyte, and the superior electrochemical properties make it desirable for use in advanced electric, electronic devices, and hybrid vehicles. |
