Directional synthesis of tin oxide@graphene nanocomposites via a one-step up-scalable wet-mechanochemical route for lithium ion batteries

Abstract

Directional synthesis of SnO₂@graphene nanocomposites via a one-step, low-cost, and up-scalable wet-mechanochemical method is achieved using graphene oxide and SnCl₂ as precursors. The graphene oxides are reduced to graphene while the SnCl₂ is oxidized to SnO₂ nanoparticles that are in situ anchored onto the graphene sheets evenly and densely, resulting in uniform SnO₂@graphene nanocomposites. The prepared nanocomposites possess excellent electrochemical performance and outstanding cycling in Li-ion batteries.
