Lithium‐Sulfur Batteries: Ultrafine Co3Se4 Nanoparticles in Nitrogen‐Doped 3D Carbon Matrix for High‐Stable and Long‐Cycle‐Life Lithium Sulfur Batteries (Adv. Energy Mater. 19/2020)

In article number 1904273, Dehua Zhu, Wei Han and co-workers graft highly conductive and catalytic Co3Se4 nanoparticles on the surface of a N-doped 3D carbon matrix as a sulfur host for lithium-sulfur batteries. The material delivers an excellent cycling performance after five months of operation, suggesting effective inhibition of the polysulfide shuttle.
