柔性和独立式电极材料是下一代柔性能量存储和转换装置的先决条件和关键部件。然而，从连续、直接和容易的方法制备这些材料仍然是一个挑战。在此，我们报道了一种柔性的复合膜与硅氧化物装饰在少壁碳纳米管，它可以连续制造，并直接从反应器的热区绘制。该复合膜可容易地用于电化学锂离子存储，具有高的和可逆的比容量、良好的倍率性能和优异的循环性能。这些特殊的特性使其非常有希望用于灵活的储能和其他新兴应用。(C)2019爱思唯尔有限公司版权所有。
Flexible and free-standing electrode materials are prerequisite and key components for next-generation flexible energy storage and conversion devices. However, it is still a chanllenge to fabricate these materials from a continuous, straightforward, and facile method. Herein, we report a flexible composite film with silicon oxides decorated on few-walled carbon nanotubes, which can be continuously fabricated and directly drawn from the hot zone of the reactor. The composite film can be readily used for electrochemical lithium ion storage with high and reversible specific capacity, good rate capability, and excellent cycling performance. These exceptional characteristics make it very promising for flexible energy storage and other emerging applications. (C) 2019 Elsevier Ltd. All rights reserved.
