Electrospinning preparation and performance of lithium-rich manganese-based lithium ion battery cathode material

One-dimensional tube-like structure of Li1.2Mn0.54Ni0.13Co0.13O2 cathode material was synthesized by electrospinning. The effects of calcination temperature on the morphology and electrochemical performance of the battery cathode material were studied. The results show that the sample synthesized at 850℃ possesses a relatively high discharge capacity and good cyclic stability, which delivers 249.5 mAh·g-1 at the first cycle and remains 87% retention after 50 cycles at the current density of 50 mAh·g-1, owing to a relatively high ionic diffusion capability.

Key words:applied chemistry,electrospinning,lithium-rich manganese,tube-like structure,calcination temperature,electrochemical performance
