A comparative study on electrochemical performance of KOH activated carbons derived from different biomass sources - stem, seed oil extract cake, stem and floss.

In the present scenario of research, the recycling of inexpensive widely available agricultural waste/biowaste to activate carbon (AC) and procurement of value-added product has significant impact on energy storage systems, particularly in Electrochemical double layer capacitors (EDLCs). Herein, we report the production of KOH activated carbons from different biomass sources such as stem (MAC), seed oil extract cake (PPC), stem (CCC) and floss (ASC) for the said purpose. Initially, the biomass materials were pyrolyzed at 550 °C and then activated with KOH at 800 °C.
