Abstract

The layered cathode materials LiNixCo1-2xMnxO2(x=1/11, 2/11, 3/11, 4/11, 5/11) powders for lithium-ion batteries were synthesized by metal acetate decomposition technique. The evolution of the structural properties and electrochemical performances of LiNixCo1-2xMnxO2 with Co content decreased were investigated by X-ray diffraction (XRD) and rietveld refinement, scanning electronic microscopy (SEM) and galvanostatic charge and discharge cycle. The results showed that the appropriate substitution of Co by Ni, Mn could greatly improve the performances of the as-prepared materials in capacity, initial columbic efficiency, rate ability and cycle capability. Among the series of materials, the optimal performance belonged to Li Ni3/11Co5/11Mn3/11O2, which delivered an initial discharge capacity of 157.6 mAh•g-1 and preserved 150.4 mAh•g-1 after 30 cycles in the voltage range of 2.5 4.3 V at 0.2 C. Comparative cycle data at 0.5 C and 1.0 C were presented implying that the LiNi3/11Co5/11Mn3/11O2 also had a significantly improvement in rate capability.
