Abstract

Laser pyrolyzed SnO₂ nanoparticles with an option of nitrogen (N) doping are prepared using a cost-effective method. The electrochemical performance of N-doped samples is tested for the first time in Li-ion batteries where the sample with 3% of N-dopant exhibits optimum performance with a capacity of 522 mAh g_{active material}^-1 that can be obtained at 10 A g^-1 (6.7C).

Keywords: SnO2; X-ray absorption spectroscopy; laser-pyrolysis; lithium ion batteries; nitrogen doping.
