In-situ preparation of uniform and ultrafine SnO2 nanocrystals anchored within mesoporous carbon network as advanced anode materials

Abstract

Fabrication of a cooperative effect between the zero-dimensional (0D) SnO2 particles and carbonaceous material with space-confined structures has shown great potential in achieving advanced lithium-ion battery anodes (LIBs), but which is full of challenges. Herein, we report a novel and green approach for preparation uniform SnO2 nanocrystals anchored within continuous mesoporous carbon network. For the first time, the formation of SnO2 nanocrystals and in-situ carbon-coating were achieved simultaneously through the ion exchange and hydrothermal method (IEHM), and subsequent calcination further endowing the composites with robust 3D-interconnected porous structure. The resultant product consists of SnO2 nanocrystals with uniform size (2.2-3.8 nm) and continuous mesoporous carbon network, which exhibits a large surface area (257 m2 g-1) and high content of SnO2 (~70 wt. %). As a result, the as-prepared SnO2/C nanocomposites delivered a high reversible capacity of 1024.6 mAh g-1 at 200 mA g-1 even after 300 cycles as anode material for LIBs. Moreover, the facile preparation of uniform SnO2 nanocrystals through IEHM would be helpful in promoting nanostructure engineering of other metal oxide materials.
