浸渍法制备活性炭/SnO2纳米复合材料用于锂离子电池
Active Carbon/SnO2 Nanocomposite Synthesized by Impregnation for Lithium-ion Batteries
摘要
Abstract
Activated carbon/SnO2 (AC/SnO2 ) nanocomposite had been synthesized by immersing AC in ethanol solution of SnCl2·2H2O, vacuum filtration, and final sintering under Ar atmosphere. The nano-pores in AC could act as hard template as well as reaction vessel for the formation of SnO2 nanoparticles (NPs). The in-situ formed SnO2 NPs were dispersed uniformly in AC matrix. As anode material for lithium-ion batteries, AC/SnO2 delivered a reversible capacity of 752 mAh·g-1 in the first cycle and 476 mAh·g-1 after 200 cycles at a current density of 100 mA·g-1,and also exhibited good rate capability. The synthesis route reported here is facile. The content of SnO2 in AC/SnO2 can be adjusted easily by change the concentration of the SnCl2·2H2O solution.关键词
