This study reports on the transformation of biogas slurry into mesoporous carbon for supercapacitor electrodes. Pore structures have been modified by altering activation time, temperature and KOH/carbon mass ratio. The mesoporous carbons are successively developed as evidenced by type IV isotherms obtained in nitrogen sorption studies. BET, micropore and mesopore surface area of 515, 350, and 165 m...
High energy density but not at the expense of power density, large areal and gravimetric capacitances, durability, lightweight, ease of fabrication, low self-discharge rates, low cost, eco-friendly, non-hazardous components to enable scale-up and safe disposal are the desirable pre-requisites that supercapacitors are expected to satisfy so that they can bridge the gap between batteries and sole carbon...
