Abstract
- GeO<subscript>2</subscript> is a promising high-performance anode material for Li-ion batteries (LIBs) because of its high theoretical reversible capacity, low operation voltage, and high thermal stability. Herein, a simple, cheap, and easily scaled-up synthetic procedure for preparing ultrathin GeO<subscript>2</subscript>-reduced graphene oxide (RGO) sheets is proposed and realized through a freeze-drying method. The as-prepared GeO<subscript>2</subscript>-RGO show non-aggregated graphene sheets and homogeneously dispersed GeO<subscript>2</subscript> nanoparticles. As a high-performance anode material for LIBs, the composite shows a high specific capacity (1200 mAh g<superscript>−1</superscript> at current density of 100 mA g<superscript>−1</superscript>), good cycling performance, and rate capability.
