An electric double-layer capacitor (EDLC) was tested using load tests involving charging/discharging at 60°C for 17h using an electrolyte consisting of a solution of 1moll −1 of tetraethylammonium tetrafluoroborate (TEA·BF 4 ) in sulfolane (SL) in order to examine the deterioration of the properties of the EDLC, including its capacitance. The interactions between the molecules of the...
Two spherical carbons of 500 and 3000m 2 /g, respectively, activated with NaOH (M500) and KOH (M3000), were examined in relation to their carbon structure and electrochemical behavior to explain their contrast capacitances as EDLC electrode.M500 and M3000 showed capacitances per weight (F/g) and volume (F/ml) of 35 and 35 (M500), 40 and 25 (M3000), respectively. The charge profile of M500...
