Fabrication and characteristics of high-capacity LiNi0.8Co0.15Al0.05O2 with monodisperse yolk–shell spherical precursors by a facile method

The structure of yolk–shell microspheres is attractive because it exhibits excellent structural stability during lithiation; monodispersed crumpled yolk–shell spherical precursors of LiNi0.8Co0.15Al0.05O2 were obtained via a general and simple supersonic atomization method. After mixing with LiNO3, this cathode material showed a high discharge capacity of about 225.9 mA h g−1 and a good cycle performance at 0.2 C, which is higher than previously reported studies.
