In this work we report about the morphological and structural characteristic of an activated carbon (P4) tailored for use in high voltage PC-based electrolytes. In these types of electrolytes P4 displays specific capacitance of about 120 F g(-1) and volumetric capacitance of 61.6 F cm(-3), which are very promising values in view of the realization of high energy EDLCs. We show that using P4 in combination with the electrolyte 1.5 M PYR14BF4 in PC it is possible to realize EDLCs able to deliver, at 1 A g-1, specific energy and power of 34.5 Wh kg(-1) and 1.7 kW kg(-1), respectively. These values are among the highest so far reported for this type of EDLCs. Furthermore, it also displays capacitance retention higher than 85% after 50.000 cycles. Taking into account these results, P4 appears therefore a suitable candidate for the realization of high energy EDLCs. (C) 2014 Elsevier B.V. All rights reserved.
