The study on the Li-storage performances of bamboo charcoal (BC) and BC/Li₂SnO₃ composites

Bamboo charcoal/Li₂SnO₃ composites for lithium-ion batteries were synthesized by a sol-gel route. The structure, morphology, and electrochemical properties of the composites were detected by means of X-ray diffraction, scanning electron microscope, Raman spectroscopy, thermal gravimetric analysis, and electrochemical measurements. The results showed that Li₂SnO₃ particles were loaded on the surface of bamboo charcoal and some of them entered into the hole. The bamboo charcoal/Li ₂SnO₃ composites exhibited good electrochemical performance with high capacity and good cycling stability (616.5 mAh g ^-1 after 50 cycles). The composites showed a better electrochemical property than Li₂SnO₃ and bamboo charcoal.
