摘要
Novel Cd2SnO4-SnO2 hybrid micro-cubes assembled from fine nanoparticles were successfully prepared through a facile hydrothermal method followed by thermal treatment. The NH4F used in our experiment plays an important role in the formation of the Cd 2SnO4-SnO2 micro-cubes. When configured as an anode material for lithium-ion batteries (LIBs), the micro-cubic Cd 2SnO4-SnO2 hybrid exhibited an enhanced reversible capacity of 523.4 mAh g-1 at 100 mA g-1 after 25 cycles compared to pristine Cd2SnO4 and SnO 2. These results indicate that this hybrid can be a promising anode candidate for LIBs. The improved electrochemical performance of the Cd 2SnO4-SnO2 hybrid may in general be attributed to the synergetic effect of the small diffusion length in the nanoparticle building blocks as well as the hybrid structural features.
