a b s t r a c t This paper presents the results from the investigation of the influence of ion size on the capacitance behaviour of TiC-derived carbon (CDC) powders in the ethyl-methylimmidazolium-bis(trifluoromethane- sulfonyl)imide ionic liquid (EMI, TFSI) used as neat electrolyte at 60 ◦C or as salt dissolved in acetonitrile and tested at room temperature. These studies were carried ou…
