Abstract

Abstract: Considerable progress has been achieved in developing supercapacitor materials with desirable charge storage properties; however, uniting energy density ( E S ) and power density ( P S ) in a single device is an elusive issue. We have explored diverse range of materials and structures such as (i) activated carbon from bio-resources, (ii) ceramic electrochemical materials as nanoparticles, nanowires, and nanoribbons, and (iii) layered materials to overcome this issue. An E S of ∼52.6 Wh kg -1 @ P S of ∼15000 W kg -1 is delivered using nanowire nanocomposites based device which appear to be the best ever achieved in supercapacitor charge storage mode employing aqueous alkaline electrolytes.
