dc.description.abstract |
Carbon-monolith electrodes for supercapacitors were prepared from GMs (green monoliths) made from
pre-carbonized fibers of oil palm EFB (empty fruit bunches) and GMs of pre-carbonized EFB fibers
exposed to gamma radiation at 5 kGy, 15 kGy, and 20 kGy. GMs and irradiated GMs were carbonized and
activated to prepare ACM (activated-carbon-monolith) electrodes. The gamma radiation affected the
pore structure of the ACM electrodes and the electrochemical performance of the supercapacitors;
irradiation doses of 0 kGy, 5 kGy, 15 kGy and 20 kGy produced specific capacitances of 121 F g 1,
196 F g 1, 11 F g 1, and 12 F g 1, respectively. The irradiation dose of 5 kGy appears to be optimum and
produces a specific power and specific energy of 236 W kg 1 and 5.45 W h kg 1, respectively, representing
34% and 60% increases over ACM electrodes prepared from non-irradiated GMs. |
