Preparation and electrochemical characterization of flower-like Li1.2Ni0.17Co0.17Mn0.5O2 microstructure cathode by electrospinning

Flower-like Li1.2Ni0.17Co0.17Mn0.5O2 microstructures were prepared by a simple one step low-temperature electrospinning method. The morphological changes occurred with temperature increase from 500 °C to 700 °C. Scanning electron microscopy showed that flower-like Li1.2Ni0.17Co0.17Mn0.5O2 after heat treatment at 600 °C was composed of nanoplates with an open porous structure. Flower-like electrode with well-organized porous structure can be attributed to the favorable shape to facilitate the diffusion of lithium ions. Flower-like Li1.2Ni0.17Co0.17Mn0.5O2 microstructures showed a high discharge capacity of 235 mA h g−1 during the first cycle compared to other electrode materials.
