Abstract

Yolk-shell-structured metal sulfide powders are developed for the first time. The yolk-shell SnS powders with a distinctive SnS@void@SnS configuration exhibit superior electrochemical properties for lithium-ion batteries even at high current densities due to their unique structure. The simple two-step process introduced in this manuscript can be applied to the preparation of various types of yolk-shell-structured metal sulfide powders.
