Preparation of high-performance activated carbons for electric double layer c…

Abstract Two kinds of mesophase pitches with different softening points were prepared at different soaking times and directly acti-vated with KOH to study the effects of the softening point on the textural characteristics of the resulting activated carbons and their be-havior as electrodes in capacitors. Results show that the softening points of the two mesophase pitches are 280 and 330 °C, …
