Nanocomposites containing Mn₃O₄ and MnOOH dual-nanocrystals on N-doped graphene sheets were prepared using a solvothermal method. Nanostructure and rate of dual-nanocrystals in the composites can be adjusted, having effects on their electrochemical performance. The nanohybrid NG-36 is composed of 1D MnOOH nanowires, Mn₃O₄ nanotetragonals and electroconductive N-doped graphene matrix. Experimental data for NG-36 reveals a high rechargeable specific capacity of 341.5 mA h g⁻¹ at a current density 3 A g⁻¹ after 500 cycles, resulting from synergetic effects among the components.
