A graphene-pure-sulfur sandwich structure for ultrafast, long-life lithium-sulfur batteries

Abstract

A unique sandwich structure is designed with pure sulfur between two graphene membranes, which are continuously produced over a large area, as a very simple but effective approach for the fabrication of Li-S batteries with ultrafast charge/discharge rates and long lifetimes. © 2013 WILEY-VCH Verlag GmbH & Co.
