摘要/Abstract

摘要：

开发了一种制备大面积CNT/Si柔性自支撑薄膜的方法，制备的CNT/Si复合薄膜尺寸可调且具有良好的柔性。作为锂离子电池负极，薄膜中硅的负载量对电极比容量及循环稳定性有显著影响。硅负载量为52%的CNT/Si复合电极表现出优良的电化学性能，1 A/g电流密度下电极充电比容量为1156 mA·h/g，循环200圈可逆充电比容量为975 mA·h/g，容量保持率达84%。

Abstract:

A method for preparing large-area CNT/Si flexible self-supporting film has been developed. The prepared CNT/Si composite film is adjustable in size and has good flexibility. As the anode of lithium-ion battery, the silicon load in the film has a significant effect on the specific capacity and cycle stability of the electrode. The CNT/Si composite electrode with 52% silicon load shows excellent electrochemical performance. The specific charge capacity of the electrode is 1156 mA·h/g at the current density of 1 A/g, 975 mA·h/g at the reversible charge capacity of 200 cycles, and the capacity retention rate is 84%.
