Design of Porous Structure of Activated Carbons from Vegetable Wastes for Electrode Materials of Supercapacitors Вased on Non-aqueous Electrolytes

The possibilities of using activated carbons (ACs) from vegetable biomass as electrode materials of supercapacitors based on organic electrolytes and ionic liquids are considered. It is noted that the ACs used in supercapacitors should have a number of characteristics, the most fundamental of which are textural: specific surface area by BET not less than ~1500 m 2 /g and the presence of a high proportion of mesopores. Studies on the use of two types of vegetable wastes (rice husk and pine nut shell), as well as two methods of chemical activation (alkaline/carbonate and phosphoric acid) have been carried out, as a result of which ACs with the required textural characteristics were obtained.
