Metal sulfides are promising materials for sodium-ion batteries (SIBs) owing to unique structures and high theoretical capacity. However, issues like poor conductivity, large volume changes, polysulfide dissolution limit practical application. This study introduces a novel Christmas tree-like heterostructure composed of Bi2S3 VS4 encapsulated in nitrogen-doped carbon shell (Bi2S3/VS4@CN), synthesized by sulfurizing dopamine-coated BiVO4 precursor. The situ synthesis ensures excellent lattice...
Lithium–sulfur (Li–S) battery has been recognized as one of the most promising energy systems due to its high specific capacity and density. However, instinct defects, such shuttle effect lithium polysulfide (LPS), low conductivity, volume expansion cathode sulfur (S), seriously hinder commercialization process. Herein, a hierarchical vanadium trioxide (V2O3) core–shell sphere, which is self-assembled from zero-dimensional (0D) nanoparticles integrated with 2D nanosheets co-doped cobalt (Co)...
