EDLCs based on the modified coconut shell raw material were manufactured with 1-Ethyl-3-methylimidazolium tetrafluoroborate (EMImBF4) as an electrolyte and a typical organic electrolyte based on acetonitrile. Three types of modification of the carbon material with different micro- to mesopore ratios were applied as the positive or negative electrode and tested. Obtained results showed different characteristic capacitances of 150–350 Fg−1, strongly dependent on the type of carbon material. Asymmetric EDLCs were manufactured from different carbon materials as positive and negative electrodes and a mass electrode fitting provided with an EDLC working at 3 V with a specific energy of 68.6 Wh kg−1 and power density of 36 W kg−1.
► Coconut raw materials were tested as electrodes for EDLC.
► Ionic Liquid and Et4NBF4/AN were used as electrolyte and compared.
► The highest capacitances for Carbon/Ionic liquid system have been observed.
► Optimisation of the mass electrodes improve characteristics of the EDLC.
