Abstract

Abstract : Nanocomposites containing Mn3 O4 and MnOOH dual-nanocrystals on N-doped graphene sheets were prepared as LIBs anode using a solvothermal method. Abstract : Nanocomposites containing Mn3 O4 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, Mn3 O4 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.
