Microwave Synthesis of Nano-Sized SnO2 for Lithium-Ion Batteries
SnO2 nanoparticles were successfully synthesized by the microwave heating. The crystallite size of the SnO2 nanoparticles was estimated to be about 3 nm from the Scherre’s equation. The initial lithium insertion capacity of the SnO2 nanoparticles was 2110 mAh/g which is larger than that of the micro-sized commercial SnO2 product. The rechargeable capacity at 10 cycles was 1060 mAh/g, and the capacity retention over the tenth cycles was about 50 %.
