摘要：
Layered transition metal oxide LiNi(x)Co(y)MnzO(2) cathode materials with different Li amount were successfully synthesized via co-precipitation method. Monodispersed Li[Ni0.5Co0.2Mn0.3]O-2 and Li-rich Li-1.1[Ni0.5Co0.2Mn0.3]O-2 spherical agglomeration consisted of secondary particles, which is favorable for the higher tap-density of materials, can be easily obtained. The pouch-typed cells with obtained materials were assembled to investigate electrochemical performance at level of full-cell. The results show that the assembled pouch-typed full-cells with Li-rich sample present higher capacity, better rate capability and cycle life.
