A new approach was designed to synthesize tin-nanoparticles encapsulated in elastic hollow carbon spheres (TNHCs) with uniform size, in which tin nanoparticles with a diameter <100 nm were encapsulated in one thin hollow carbon sphere. The content of tin is up to over 70% by weight, andthe void volume inside the TNHCsis as high as 70–80%, which can accommodate the volume after expansion. This tin-based nanocomposite exhibits a great potential as an anode materials for lithium-ion batteries.
