Carbon nanospheres derived from Lablab purpureus for high performance supercapacitor electrodes: a green approach

in 5 M KOH electrolyte for carbon nanospheres synthesized at 800, 700 and 500 °C, respectively. These are on a par with those of prior electrodes made of biologically derived carbon nanospheres but the cycle lives were remarkably higher than those of any previous efforts. The electrodes showed 94% c... View More
