Lithium-sulfur batteries (LSBs) are considered as one of the most promising next-generation energy-storage devices because of their high energy density. However, the long-term use of LSBs is mainly limited by polysulfide shuttling and cathode structural degradation caused by volume changes during charging and discharging. To address these issues, a multifunctional, high-performance aqueous binder is developed by modifying a natural polysaccharide with multi-walled carbon nanotubes (MWCNTs).

- - The study explores the creation of porous carbon materials combined with metal phosphides to improve the performance of lithium-sulfur (Li-S) batteries by preventing sulfur poisoning and enhancing catalytic activity.
- - A new method was developed to produce ultra-small CoP nanoparticles on hollow carbon nanospheres, utilizing spherical polyelectrolyte brushes as a template, resulting in improved particle size control.
- - The optimized CoP@C structure enhances lithium-ion diffusion and polysulfide conversion kinetics, leading to Li-S batteries with a high initial discharge capacity and minimal capacity decay over cycles.
