A self-encapsulated porous Sb–C nanocomposite anode with excellent Na-ion storage performance

In this study, a self-encapsulated Sb–C nanocomposite as an anode material for sodium-ion batteries (SIBs) was successfully synthesised using an SbCl₃–citrate complex precursor, followed by a drying and calcination process under an inert N₂ atmosphere.
