Gel based sulfur cathodes with a high sulfur content and large mass loading for high-performance lithium–sulfur batteries

Abstract

A bacterial cellulose based carbon nanoribbon aerogel was employed for a gel-based sulfur cathode, simultaneously achieving both a high sulfur content (90%) and a high sulfur loading (6.4 mg cm⁻²) with a large capacity of 943 mA h g⁻¹or 5.9 mA h cm⁻².
