Hollow Li1.2Mn0.54Ni0.13Co0.13O2 micro-spheres synthesized by a co-precipitation method as a high-performance cathode material for Li-ion batteries

摘要

Hollow Li1.2Mn0.54Ni0.13Co0.13O2 micro-spheres were successfully synthesized by a co-precipitation method. The micro-spheres deliver an initial discharge capacity of 296 mA h g(-1) and a coulombic efficiency of 83.4% at a current density of 30 mA g(-1). Furthermore, the micro-spheres exhibit an excellent rate capability (150 mA h g(-1) at a current density of 1500 mA g(-1)) and a high reversible discharge capacity of 227 mA h g(-1) after 100 cycles at a current density of 60 mA g(-1).
