Activated carbon has an enormous demand for its broad purposes in batteries, supercapacitors, wastewater remedy, and many others. Activated carbon possesses a porous morphology, which facilitates its enhanced thermal stability, and floor space. Researchers using agro-waste have centered on assembly the excessive demand of low-cost activated carbon manufacturing. This paper reviews coconut-shell-derived activated carbon ready by the thermal and chemical activation processes. The ready samples are investigated for his or her structural, morphological, elemental composition, electrochemical properties, and useful teams. The ready samples evidenced the amorphous nature, and a few graphitic disordered, as confirmed by the x-ray diffraction (XRD) and Raman investigations. The morphological evaluation demonstrated the formation of a nanoflakes-like construction; nevertheless, one other pattern ready with chemical activation endorsed the porous carbon nanostructures. Moreover, we’ve got examined electrochemical properties and explored.
