Abstract

The regeneration of metal sulfides during the delithiation process is the key to achieving cyclic stability in electrode materials. A graphene‐supported peony‐like MoS2 nanocomposite with a long cycle life and a high rate capability is designed for this purpose. The synergistic effects of the MoS2 hierarchical structure and graphene can effectively improve the lithium diffusion dynamics and conductivity, thus greatly suppressing the oxidation of Li2S to polysulfides by improving the reversibility of the conversion reaction.
