Uniformly anchoring Sb2O5 nanoparticles on graphene sheets via Co2+-induced deposition for enhanced lithium/sodium-ion storage

A Co–Sb 2 O 5 /rGO nanocomposite was prepared by a facile Co 2+ -induced deposition process. The interactions between Sb 2 O 5 and rGO were enhanced by initial in situ formation of CoSb 2 Sb 6 , resulting in greatly improved lithium-ion storage performance.
