A high performance carrier for SnO2nanoparticles used in lithium ion battery

Abstract

Ferrocene-encapsulated single-walled carbon nanotubes (Fc@SWNTs) are developed as carriers for attaching SnO₂. When Fc@SWNTs coated with SnO₂ 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.
