In this study, biochar samples were prepared by conversion of biomass feedstock (corn stover) via catalytic hydrothermal liquefaction (HTL) and later used as electrode material in conjunction with sol-gel derived perovskite based mixed (Mn,Ti)-oxides (Mn:Ti precursors 65:35 wt%) for asymmetric supercapacitors. The HTL reaction was performed with 5wt%. Ca(NO3)2 at 250oC for 1 hour. The biochar obtained after the HTL reaction was activated with KOH and further thermally treated at 400oC for 1 hour. The activated porous biochar samples were analyzed by BET surface area analyzer. In asymmetric supercapacitors (ASC) configuration, the energy storage potential was studied using cyclic voltammetry.
