“…Thus, the mechanism of alloying lithiation is proved. Meanwhile, the discharge/charge capacity of the 20% MnO2/CNFs remains higher than that of the 5% MnO2/CNFs, which indicates not only high performance, but also excellent battery reversibility [39,40]. The discharge/charge graphs of 5% MnO 2 /CNFs and 20% MnO 2 /CNFs at a current density of 0.1 A g −1 are displayed in Figure 7a,b.…”

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

High-performance anodes are contributed to nanostructure of transition metal oxides for rechargeable Li-ion batteries (LIBs). In this work, we report the fabrication of high-performance anode materials for lithium-ion batteries, MnO2 nanotube directly grown into fabrics of carbon nanofibers, the MnO2/Carbon nanofibers (CNFs) were investigated by X-ray diffraction, scanning and transmission electron microscopies. When tested as the anode material in LIBs, the MnO2/CNFs exhibit superior performance and excellent long cycling performance with a reversible capacity of 835 mA h g-1 at 0.1 A g-1 after the 133 th cycle, a high initial specific capacity of 1094 mA h g-1 at a current density of 0.1 A g-1. The MnO2/CNFs demonstrates notable specific capacities, specifically, with a coulombic efficiency of 99.5 %, both stability and capacity are conspicuously above literature data. These impressive results indicate that MnO2/CNFs has great potential for high-energy and high-power energy storage applications.
