Heterostructured CoS2/NiS2 nanoparticles encapsulated in bamboo-like carbon nanotubes as a high performance anode for sodium ion batteries

Heterostructured binary metal-sulfide CoS₂/NiS₂ compounds encapsulated in bamboo-like carbon nanotubes (CoS₂/NiS₂@B-CNT), were prepared and applied as an anode for sodium ion batteries.
