Novel Large‐Scale Synthesis of a C/S Nanocomposite with Mixed Conducting Networks through a Spray Drying Approach for Li–S Batteries

A woolball-like nanocomposite of commercial carbon/sulfur microspheres with sulfur content over 81 wt% is successfully fabricated using a new one-step spray drying approach. The designed polyporous electrodes with a sulfur loading of 2.5 mg cm−2 exhibit excellent Li storage performance. This facile and cost-effective process of fabricating the carbon/sulfur nanocomposite shows great promise for large-scale application in practical lithium–sulfur batteries.
