摘要
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 Li 2S 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. © 2014 WILEY-VCH Verlag GmbH & Co.
