We here report on the preparation and Li-ion battery anode application of ultrasmall Sn nanoparticles (∼5 nm) uniformly embedded in spherical hollow carbon. The novel Sn-C composite shows a high Li-storage capacity (743 mA h g at 0.5 A g) with unprecedentedly high cyclic stability (92.1% capacity retention after 6000 cycles at 4 A g).
我们在此报道了均匀嵌入球形中空碳中的超小锡纳米颗粒（约5纳米）的制备及其在锂离子电池阳极中的应用。这种新型的锡-碳复合材料展现出高储锂容量（在0.5 A g下为743 mA h g）以及前所未有的高循环稳定性（在4 A g下循环6000次后容量保持率为92.1%）。
