MnO2/Carbon Nanofibers Material as High-Performance Anode for Lithium-Ion Batteries

MnO2 has advantages such as the simple and diverse preparation methods, low cost high theoretical capacity, but its industrial application is affected by poor conductivity fast attenuation of cycle performance. In order to improve conductivity, battery capacity performance, MnO2/carbon nanofibers (MnO2/CNFs) are obtained using electrospinning technology, electrochemical performance was confirmed XRD, SEM, TEM. Confirmed comparison, 20% MnO2/CNFs exhibit superior excellent long cycling with a reversible 835 mA h g−1 at 0.1 A after 133th initial specific 1094 current density g−1. The have notable capacities coulombic efficiency 99.5%, which greatly reaction rate. This can also be used flexible electrode material because good flexibility. Due fact that carbon better electron/ion it shows kinetics.
