Boosting the lithium storage of SnO2 nanoparticles by anchoring onto an interconnected carbon nanoribbons assembled 3D architecture

Herein, the improvement in the electrochemical properties of the SnO 2 anode has been demonstrated through constructing flexible carbon nanoribbons supporting and extra carbon anchoring. And the as-constructed SnO 2 -based composite has been studied by XRD, Raman, TEM, and XPS characterizations. The obtained results indicate that the rutile phase SnO 2 nanoparticles are anchored on 3D carbon nanoribbons by an extra amorphous carbon. As a result, this composite shows superior electrochemical properties with high capacities of 794 and 510 mAh g −1 at 200 and 1000 mA g −1 even after 500 and 1000 cycles, respectively, exhibiting great promise for a progressive LIB anode material.
