本文报道了一种在轻质碳纤维集流体上的多孔硅碳负极用于锂离子电池。这种Si-C阳极是通过直接沉积在碳纤维垫上的Si-聚（丙烯腈-共-丙烯酸甲酯）前体的一步碳化来合成的。碳纤维电流收集器允许更高的活性材料负载，导致高的能量质量比和面积比。所获得的Si-C电极表现出上级的总容量、循环能力和倍率容量。(C)2010爱思唯尔有限公司版权所有。
A porous silicon-carbon anode on a lightweight carbon fiber current collector is reported here for lithium-ion batteries. This Si-C anode was synthesized through a one-step carbonization of a Si-poly(acrylonitrile-co-methyl acrylate) precursor, which was directly deposited on a carbon fiber mat. The carbon fiber curent collector allows higher loading of active materials, resulting in high energy to mass and area ratios. The obtained Si-C electrode demonstrated superior overall capacity, cyclability, and rate capacity. (C) 2010 Elsevier B.V. All rights reserved.
