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 C rate between 2.8 and 4.3 V.
