Abstract

We report the facile synthesis of a porous-carbon (PC) nanostructure via a dual-mode activation process. Its PC nanostructure, which was activated via the release of HF and NaOH during a pyrolysis of Poly(vinylidene fluoride-co-hexafluoropropylene), provided a large surface area above 2000 m2 g-1. The fabricated PC was composited with sulfur via melt diffusion (PC/S), and the resulting compound was evaluated with galvanostatic cycling for use in applications of lithium-sulfur batteries. The PC/S electrode demonstrated over 730 mA h g-1 of reversible capacity after 100 cycles.
