Abstract

A nanostructured C‐Li2S composite nanopowder is prepared via a scalable, high‐throughput solution‐processing method based on the steric separation of freshly nucleated Li2S nanoparticles and their self‐assembling. Each 100–200 nm particle is composed of smaller 5–20 nm Li2S nanoparticles uniformly distributed within a rigid carbon matrix. When used as a cathode material for Li cells, this composite demonstrates high rate performance, near‐theoretical capacity utilization, and excellent cycle stability.
