「TEEP@AsiaPlus」KSU: Asymmetri Supercapacitor, Biomass, Gel Electrolyte

Supercapacitors and batteries have been proven to be the most effective energy storage devices for renewable energy sources. However, high conductivity carbon materials, graphene and carbon nanotube, used in supercapacitors are often derived from nonrenewable resources under harsh environments. Therefore, it is in urgent to develop sustainable alternatives using more greener and low-cost methods. Biomass resources are inexpensive, abundant, and sustainable, which can be converted into ‘green’ carbon materials. In this study, hierarchical porous carbon materials derived from renewable biomass materials and KOH activation, with a focus on the preparation conditions. Porous manganese cobalt oxide (MCO) films were prepared directly on a conductive stainless steels (SS) mesh substrate via electrodeposition and an annealing treatment as positive electrodes. Hierarchical porous carbons were coating on conductive nickel (Ni) foam substrate as negative electrodes. Further, utilizing (MCO/SS) as a positive electrode, a hierarchical porous carbon (HPC)/Ni as a negative electrode, with carboxymethyl cellulose (CMC)-Lithium nitrate (LiNO3) gel-electrolyte as the HPC/MCO asymmetric supercapacitor was fabricated. The electrochemical catalytic activity of the as-prepared asymmetric supercapacitor was evaluated using galvanostatic charge and discharge cycling measurements to evaluate the stability and performance.
