Uniform Mn3O4 nanoparticles with a suitable diameter of 40 nm were prepared by the water bath method and exhibited outstanding electrochemical performance as anodes for lithium-ion batteries, showing good capacity and rate capability.
The Mn3O4 nanomaterials were widely investigated due to their potential application as anodes for lithium-ion batteries. Uniform Mn3O4 nanoparticles with a suitable diameter of 40 nm were designed and prepared by the water bath method to solve the low conductivity and the pulverization during cycling. The Mn3O4 nanoparticles electrodes exhibited an initial discharge capacity of 1288 mAh/g with an initial coulombic efficiency of 65% at 100 mA/g. At 200 mA/g, the reversible capacity increased to 1345 mAh/g after 190 cycles. The specific capacity increased to 547 mAh/g and 691 mAh/g when back to 200 mA/g and 100 mA/g, indicating the exceptional rate capability. The outstanding electrochemical performance of the Mn3O4 nanoparticles results from the suitable size of the nanoparticles and the increased conductivity during cycles. The Mn3O4 nanoparticles prepared with the water bath method have the potential application as anodes for lithium-ion batteries.
