Lithium–Sulfur Batteries: Compactly Coupled Nitrogen‐Doped Carbon Nanosheets/Molybdenum Phosphide Nanocrystal Hollow Nanospheres as Polysulfide Reservoirs for High‐Performance Lithium–Sulfur Chemistry (Small 40/2019)

In article number 1902491, Yuwei Zhang, Li Niu, and co-workers report a novel polysulfides immobilizer for Li-S batteries.3D hierarchical nitrogen-doped carbon nanosheets/molybdenum phosphide nanocrystal hollow nanospheres (MoP@C/N HCSs) not only provide strong physical trapping and chemical anchoring toward polysulfides, but also accelerate the kinetics of the polysulfides redox reaction and lower the Li 2 S nucleation/ dissolution interfacial energy barrier and self-discharge capacity loss in working Li-S batteries, simultaneously.
