通过在电纺碳纳米纤维中嵌入纳米硅作为合金化介质，开发了一种新型储能材料。由这些碳/硅复合纳米纤维制成的阳极结合了碳(循环寿命长)和硅(高锂存储容量)的优点。它们表现出良好的电化学性能，表现为大的可逆容量，相对较好的容量保持率和插入/提取锂的优异倍率性能。因此，它们很有希望成为高性能电池储能的负极候选者。(C)2009爱思唯尔有限公司。保留所有权利。
A new energy-storage material has been developed by embedding Si nanoparticles as an alloying medium in electrospun carbon nanofibers. Anodes made from these carbon/Si composite nanofibers combine the advantages of both carbon (long cycle life) and Si (high lithium-storage capacity). They exhibit good electrochemical performance in terms of large reversible capacity, relatively good capacity retention and excellent rate capability upon insertion/extraction of lithium. As a result, they are promising anode candidates for storing energy in high performance batteries. (C) 2009 Elsevier Ltd. All rights reserved.
