Biomass-derived porous activated carbon from coconut husk for high-energy density symmetric supercapacitors / Farah Adriana Md Zin

Biomass-derived porous activated carbon materials are readily available, renewable, sustainable, and capable of producing great results without costing a lot of money, thus they have received great deal of interest in energy-storage devices, particularly supercapacitors. This research describes the preparation of activated carbon electrodes from coconut husks through chemical activation method at impregnation ratios of 1:1 and 1:3. Potassium hydroxide (KOH) is used as an activator during chemical activation. This research aims to observe the effects of mixing activating agents at different impregnation ratios on the yielding percentage of activated carbon in the samples obtained during the research. Chemical assessments of the final product, as well as the percentage of carbon yield and ash content, are assessed utilising a mathematical formula method at the end of this research.
