Core-shell Si nanowires are very promising anode materials. Here, we synthesize vertically aligned carbon nanotubes (CNTs) with relatively large diameters and large inter-wire spacing as core wires and demonstrate a CNT-Si core-shell wire composite as a lithium ion battery (LIB) anode. Owing to the rationally engineered core structure, the composite shows good capacity retention and rate performance. The excellent performance is superior to most core-shell nanowires previously reported.
核壳结构硅纳米线是一种很有前途的阳极材料。在此，我们合成了作为核丝的具有较大直径和较大丝间间距的垂直排列碳纳米管（CNTs），并展示了一种作为锂离子电池（LIB）阳极的 CNT-Si 核壳线复合材料。由于合理设计的核结构，该复合材料表现出良好的容量保持率和倍率性能。其优异的性能优于之前报道的大多数核壳纳米线。
