Abstract

Layered lithium transition metal oxide LiNi0.5Co0.2Mn0.3O2 cathode materials were successfully obtained through a simple carbonate co-precipitation method. Monodispersed Li[Ni0.5Co0.2Mn0.3]O2 spherical agglomeration consisted of nanoscale secondary particles enable material to be higher energy and powder density. Pouch-typed cells were assembled to investigate electrochemical performance of Li[Ni0.5Co0.2Mn0.3]O2 at level of full-cell. The results show that the assembled pouch-typed full-cells present higher capacity, excellent rate capacity, and cycle life, which is due to its monodispersed uniform morphology with nanoscale secondary particles.
