“…Due to the limitation of ion diffusion in the pores of carbon materials, the specific capacitance of the cells were decreased while increasing the current density. This is because, at higher current densities, the electrolyte ions cannot cover all the electro active sites of the electrodes, which reduces the energy storage capacity of the supercapacitors . The obtained specific capacitances of the cells fabricated using activated biocarbons from jatropha oilcake are comparable with the literature values as shown in Table .…”

“…Using 6 m KOH as electrolyte, the maximum energy density of 8.9 W h kg −1 was achieved at a power density of 125 W kg −1 , whereas it was still 5.6 W h kg −1 even if power density increased to 4563 W kg −1 . Although the energy density decreased with the increase in power density, C‐Cs3.8 displayed comparable or superior energy–power performance compared with those in the literature in aqueous electrolyte, as shown in Table . Compared with aqueous electrolyte, higher energy density of C‐Cs3.8 electrode can be successfully achieved in organic electrolyte.…”

“…In contrast, an energy density of 4.5 W h kg À1 is still retained even when the power density was increased to 12.5 kW kg À1 , which shows an enhanced rate performance among porous materials reported in literature. 25,45,[50][51][52][53]…”
