The role of the tin precursor in tuning TMS@carbon yolk-shell nanospheres for enhanced sulfur utilization.

ABSTRACT: Lithium-sulfur (Li-S) batteries are promising candidates for future energy storage systems because of their abundant theoretical capacity and low cost. However, challenges such as polysulfide shuttle effects and poor conductivity hinder their practical use. Yolk-shell structured nanocomposites offer a promising avenue for addressing the challenges in Li-S batteries. Herein, one-pot hydrothermal synthesis of yolk-shell SnS₂@MoS₂@C nanospheres is reported, where the inclusion of the tin precursor plays a pivotal role in tuning these unique nanostructures. The resulting architecture provides enlarged interlayer spacing, internal voids, and robust stability, facilitating efficient ion transport and volume buffering. Electrochemical evaluations reveal a high initial capaci
