摘要：

Honeycomb-like porous carbons (HPCs) were synthesized from coal tar pitch using melamine as soft template coupled with KOH activation. The surface area of HPCs reaches 2038 m(2) g (1). As electrodes for supercapacitors, the HPCs show a high specific capacitance of 221 F g (1) at 0.05 A g (1) in 6 M KOH electrolyte, an excellent rate performance with capacitance remaining at 81.0% at 20 A g (1) and a superior cycle stability with 95.3% capacitance retention after 5000 cycles. This work paves a low-cost way for large scale production of electrode materials for commercial supercapacitors. (C) 2017 Elsevier B.V. All rights reserved.
