Mn_3O_4 is viewed as an attractive candidate for rechargeable aqueous zinc-ion battery cathode materials due to the advantages of low cost, eco-friendly nature as well as high capacity. However, it faces inherently poor electronic conductivity and poor cyclability during battery cycling. To improve the electrochemical performance, Mn_3O_4 nanoparticles anchored on carbon nanotubes (CNTs@Mn_3O_4) were fabricated by a facile one-step solution process at low temperature. Benefiting from the synergistic effect of nanoscale Mn_3O_4 and 1D CNTs, the conductivity and electrochemical performance of Mn_3O_4 are significantly improved. The prepared CNTs@Mn_3O_4 nanocomposites deliver a discharge capacity of 310 mAh g~(-1) at 100 mA g~(-1) and maintain 123 mAh g~(-1) at 1000 mA g~(-1) after 500 cycles, demonstrating good rate capability and cycling performance as a promising cathode material for low-cost neutral zinc-ion battery.
