Supercapacitors (SCs) are promising energy storage devices for next-generation flexible electronics due to their high-power density, fast charge-discharge rates, and long cycle life. This study reports the electrochemical conversion of Mn3O4 into layered S-MnO2 via cycling in a sodium nitrate (NaNO3) electrolyte. The impact of cycling on the structural and electrochemical properties is investigated, with S-MnO2 obtained after 10 cycles (S-MnO2:10C) showing a high specific capacitance (Csp) of 174 F g- 1 at 1 A g-1. Flexible asymmetric supercapacitors (ASCs) are then fabricated using S-MnO2:10C as the positive electrode and either reduced graphene oxide (rGO) or Ti3C2Tx MXene as the negative electrode. The S-MnO2:10C//rGO device achieves an energy density (ED) of 10 & micro;Wh cm- 2 and a power density (PD) of 1124.4 & micro;W cm- 2, while the MXene-based ASC offers
