Abstract:
N-doped Si nanoparticles were prepared synchronously by nitridation of Mg2Si. The existence of nitrogen doping can be demonstrated by the XPS spectrum and EELS energy-filtered images. When the N-doped Si nanoparticles were used as an anode for Li-ion batteries, a high reversible capacity of 2595 mA h g(-1) at 0.36 A g(-1) after 40 cycles, and 805 mA h g(-1) at 3.6 A g(-1) after 800 cycles could be obtained.
