Electrocatalysts of Mn and Ru oxides loaded on MWCNTS with 3D structure and synergistic effect for rechargeable Li-O2 battery

Mn and Ru oxides loaded on MWCNTs with 3D Structure is fabricated through a simple one-pot hydrothermal method and applied as cathode for Li-O2 battery. With the synergy effect of nanostructure and efficient catalyst, it delivers a high capacity of 20910 mAh g−1, a low overpotential of 0.68 V at 50 mA g−1, and stable operation exceeding 120 cycles at 1 A g−1.298
