Abstract

A facile hard-templating method has been developed to prepare highly N-doped carbon/sulfur cathodes with thickness < 200 [small micro]m and large areal mass loading (> 2.5 mgsulfur cm-2). Lithium-sulfur batteries using this free-standing and binder-free hierarchical hybrid design exhibit good cycling performance, with stable areal capacities of 3.0 mAh cm-2, owing to favorable properties of the carbon host.
