Firmly combination of CoMnOx nanocrystals supported on N-doped CNT for lithium-ion batteries

• One-step synthesis of Mn-Co/N-CNT has been proposed for the first time.
• Dicyandiamide act as surfactant and N source during Mn-Co deposition process.
• N-doping helps to improve the interaction between Mn-Co species and CNT.
• The Mn-Co/N-CNT shows high reversible capacity and good stability.

A novel one-dimensional CoMnOx/N-CNT composite was synthesized by binding Mn-Co nanoparticles on nitrogen doped carbon nanotubes (N-CNT) through solvothermal method and followed by high temperature pyrolysis. The as-made Mn-Co/N-CNT as LIBs anode material exhibits excellent rechargeable capability, i.e. 1028 mAh·g−1 at 200 mA·g−1. Doped nitrogen on CNT effectively increase the conductivity of the complex and the binding energy between Mn-Co nanoparticles and CNT, which lead to more stable and higher conductive complex during charge/discharge cycling process.
