Bimetallic Sulfide Sb2S3/FeS2 Heterostructure Anchored in a Carbon Skeleton for Fast and Stable Sodium Storage

Sodium-ion batteries (SIBs) are a promising substitute for lithium batteries due to their abundant resources and low cost. Metal sulfides are regarded as highly attractive anode materials due to their superior mechanical stability and high theoretical specific capacity. Guided by the density functional theory (DFT) calculations, 3D porous network shaped Sb
