A corn-like graphene–SnO2–carbon nanofiber composite as a high-performance Li-storage material

Abstract

A new kind of corn-like graphene–SnO₂–carbon nanofiber (GSCN) mixture has been successfully developed. SnO₂ nanoparticles are grown on the surface of PPy-based carbon nanofibers and enveloped by graphene layers. The GSCN anode delivers a remarkable capacity of 1246.3 mA h g⁻¹ at 0.5 A g⁻¹, which has potential for practical application.
