Microwave Synthesis and Electrochemical Properties of Ultrafine SnO2 Nanoparticles

Abstract

Abstract Ultrafine SnO2 nanoparticles were successfully synthesized by microwave heating. Transmission electron microscopy images revealed that the size of primary particles of the synthesized SnO2 was around 5 nm. The SnO2 nanoparticles worked as a rechargeable electrode material, and the initial lithium insertion capacity of the SnO2 nanoparticles was 1670 mA h g−1 which is significantly larger than that of a specimen synthesized by conventional method.
