In the present work, we report a new activating agent (NaCl: KCl) (1: 1) for the synthesis of nanoporous carbon from Java Kapok tree shell (1: 1) with different controlled temperature under inert atmosphere. Additionally, surface morphology, physico-chemical and electrochemical properties of the nanoporous carbon are characterized. The obtained Kapok shell derived nanoporous carbon possessed a large surface area of 1260 m(2) g(-1), pore volume of 0.439 cm(3) g(-1), pore size of 1.241 nm, and microspore volume of 0.314 cm(3) g(-1). The nanoporous carbon-based electrode material exhibited higher capacitance of 169 F g(-1) with 97% capacity retention after 10,000 cycles at 1 A g(-1). We believe that this new activation agent can be significant contribution in the new carbon technology for energy storage materials. (C) 2018 Elsevier B.V. All rights reserved.
