Abstract:

Lithium-sulfur batteries (LSBs) are a promising candidate for next-generation energy storage solutions. However, challenges such as the shuttling effect and sluggish Li-S reaction kinetics of lithium polysulfides hinder their practical application. In this work, we present a mixed-phase heterostructure comprising Co0.85Se and MoSe2, supported on nitrogen-doped carbon polyhedrons (NCP), as an effective sulfur host in the LSB cathode. Through a combination of theoretical calculations and experimental validation, we demonstrate that the Co0.85Se-MoSe2 heterointerface significantly enhances electron transfer efficiency, thereby boosting the overall reaction kinetics of the sulfur cathode. As a result, the Co0.85Se-MoSe2/NCP/S electrodes exhibit initial specific capacities exceeding 1500 mAh g−1 at 0.1 C and retain 666 mAh g−1 at 3 C, with a capacity fade rate of 0.044% per cycle over 500 cycles at 1.0 C. Notably, even at a high sulfur loading of 3 mg cm−2 and a reduced electrolyte volume of 6.7 μL mgS−1, the Co0.85Se-MoSe2/NCP/S electrodes maintain a capacity of 432 mAh g−1 after 100 cycles at 0.2 C. © 2025 Science Press and Dalian Institute of Chemical Physics, Chinese Academy of Sciences
