文摘

The Ni_0.8Co_0.1Mn_0.1O₂ precursor with uniform particle size for LiNi_0.8Co_0.1Mn_0.1O₂ cathode material synthesis is firstly prepared by an atomization co-precipitation (AC) method. XRD Rietveld refinement results demonstrate that LiNi_0.8Co_0.1Mn_0.1O₂ cathode material synthesized by AC method possesses good layered structure with low Li/Ni mixing degree. The obtained LiNi_0.8Co_0.1Mn_0.1O₂ material exhibits excellent rate and cycling performance. It retains 82.42% of its initial capacity (0.1 C) at a high rate (5 C). The capacity retention of LiNi_0.8Co_0.1Mn_0.1O₂ can be as high as 88.5% after 100 cycles even at 2 C rates.
