Capacitance behavior of KOH activated mesocarbon microbeads in different aque…

Abstract. A series of microporous carbons with wide scope of porosity development (surface area SDFT = 1200–2460 m2 g−1, micropore volume VDR = 0.43–1.2 cm3 g−1, average micropore width L0 = 0.9–1.5 nm) was prepared by KOH activation of coal-tar pitch derived mesocarbon microbeads (MCMB). The activated MCMB were tested as an electrode material of capacitor in two-electrode system …
