Electrospun Manganese Oxides Nanofibers Electrode for Lithium Ion Batteries: Electrospun Manganese Oxides Nanofibers Electrode for Lithium Ion Batteries

Manganese oxides nanofibers were successfully fabricated by, an electrospinning method and its electrochemical behavior was investigated as three-dimensional (3D) architecture of cathodic materials. Scanning electron microscope, X-ray diffraction and the discharge/charge curves were used to characterize their structures and electrochemical properties. Manganese oxides nanofibers are achieved after calcination at 450 degrees C. The high reversible discharge capacity reaches 160mAh/g and the discharge capacity is about 132.5mAh/g with capacity loss less than 1.0% per cycle in 50 cycling. SEM observations show that the structure of manganese oxides nanofibers is stable without the mechanical destruction of nanofibers during the Li(+) ion intercalation and deintercalation. The results demonstrate that manganese oxides nanofibers are promising cathodic materials for 3D lithium batteries.
