摘要：

Silicon is a potential next generation anode material for lithium-ion battery, however, its commercial application was hindered by its poor electronic conductivity and huge volume change upon lithiation. Herein, Si@N-doped carbon nanoparticles with commercial Si nanoparticle as the core and N-doped carbon as the shell were prepared by a facial, low-cost and scalable one-step method using ionic liquid (3-cyanopyridine/H
