Abstract

Fibres of oil palm empty fruit bunches (OPEFB), a large quantity waste material generated at palm oil mills, were converted into self-adhesive carbon grains (SACG). KOH treated SACG were added with 0, 5, 10, 15 and 20 wt. % of polypyrrole (PPy) to produce green monoliths (GMs) which were used to obtain activated carbon monoliths (ACMs) electrodes via carbonization (N2 environment) and activation (CO2 environment) for their application in symmetrical supercapacitors. Various properties of the electrode materials were examined by thermo-gravimetric analysis, X-ray diffraction and field emission scanning electron microscopy techniques. Electrochemical performance of the ACMs as electrodes was tested with 1 M H2SO4 as electrolyte using electrochemical impedance spectroscopy, cyclic voltammetry and galvanostatic charge-discharge techniques. Addition of (15-20) wt. % of PPy in GMs affects the structure, microstructure and pore structure of the ACMs and consequently leads to an enhancement of ~ (20-50) F g-1, ~ 3-6 Wh kg-1 and ~ 96-98 W kg-1 in specific capacitance (Csp), specific energy (E) and specific power (P), respectively, with respect to the electrode prepared from GMs without PPy which offers corresponding values of ~ (2-10) F g-1, 2 Wh kg-1, and 87 W kg-1.
