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

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.
