Abstract

We synthesized an electrospun SnO₂ hollow nanofibers (SnO₂ hNFs) coated with carbon and wrapped with graphene oxide layer by simple hydrothermal and electrostatic force method, respectively. Thin carbon layer as electrolyte blocking layer was formed on the SnO₂ hNFs by using glucose as a carbon source (SnO₂@C hNFs). Also, layers of graphene oxide are wrapped on SnO₂@C hNFs by the electrostatic interaction force (SnO₂@C@G hNFs). At high C rate, the average capacity of the SnO₂@C@G hNFs still kept high capacity comparing with the SnO₂ hNFs and SnO₂@C hNFs and then increased above 250% at 3 C. It also exhibits a greatly enhanced synergic effect with an extremely high lithium storage capability up to 1,600 mA h g^-1 and kept 900 mA h g^-1 after 50 cycles benefiting from the advanced structural features.
