A high performance carrier for SnO_2 nanoparticles used in lithium ion battery

摘要

Ferrocene-encapsulated single-walled carbon nanotubes (Fc@SWNTs) are developed as carriers for attaching SnO_2. When Fc@SWNTs coated with SnO_2 nanoparticles were used as anode material in lithium ion batteries, the reversible capacity remained over 900 mA h g~(-1) after 40 cycles, much higher than other carbon nanomaterials.
