It can be found that the Mn/Si ratio is a crucial factor affecting the morphology of the as-obtained products. The pristine Si nanoparticles are sphere-like particles of ~100 nm in diameter. When the Mn/Si molar ratio is 4:1, ultrafine MnCO3 nanowires less than 10 nm in diameter are obtained. The MnO@C nanowires were synthesized via polymerization–pyrolysis steps, and the excellent high-rate performance and stability of the MnO@C nanowires used as an anode in the lithium-ion battery are attributed to the unique interconnected nanostructure.
