英文摘要 | an efficient anode with a superior high-rate capability and stability remains a challenge for development of high performance li-ion batteries. we present a new concept by encapsulating 2 nm-sized sno2 nanocrystals in the channels of carbon nanotubes (sno2-in-cnts). characterization shows that the confined space does not only stabilize the small nanoparticles but also alleviates the stress caused by the large volume change of tin species during the charging-discharging process. in addition, well crystallized graphitic structure of cnts with a positive curvature provides a good contact between sno2 nanoparticles and graphene layers, and excellent electronic conductivity. as a result, sno2-in-cnts as an anode of lithium ion battery exhibit stable cyclability and superior high-rate capability relative to sno2 nanoparticles dispersed on the outer walls of cnts particularly under a high current density. the charge capacity remains about 560 ma h g(-1) after 50 cycles at 50 ma g(-1), and even around 400 ma h g(-1) at 1000 ma g(-1). additionally, the facile preparation method we have developed makes such encapsulates appealing for further optimization and applications. |
