Abstract:	Spherical Ni_0.8Co_0.15Al_0.05OOH precursor,prepared by a co-oxidation-controlled crystallization method,was used to synthesize LiNi_0.8Co_0.15Al_0.05O₂.The obtained LiNi_0.8Co_0.15Al_0.05O₂ materials showed excellent electrochemical performance,with an initial discharge capacity of 193.5 mAh/g and capacity retention of 95.1%after 50 cycles when cycled at 0.2℃rate between 2.8 and 4.3 V.

Keywords:	Li-ion battery Cathode material LiNi_0.8Co_0.15Al_0.05O₂ Co-oxidation-controlled crystallization
