摘要：
A simple one-pot reaction method was used to synthesize NiCoMn-MOF with Li+ adsorption, which was used as the precursor to prepare LiNi1/3Co1/3Mn1/3O2 cathode materials. The microscopic structural features of LiNi1/3Co1/3Mn1/3O2 were investigated using scanning electron microscopy, x-ray diffraction, and Fourier-transform infrared spectrometry. The electrochemical properties of LiNi1/3Co1/3Mn1/3O2 are investigated by charge-discharge cycles and impedance experiments. The obtained results suggest that LiNi1/3Co1/3Mn1/3O2 obtained by using NiCoMn-MOF as a precursor had uniform particle size and good crystallinity. The initial discharge capacity could reach 193 mAh g(-1) at 0.1 degrees C in the voltage range of 2.5-4.3 V. The capacity retention rate was 90% after 50 cycles at 1 degrees C. This showed that LiNi1/3Co1/3Mn1/3O2 synthesized from a NiCoMn-MOF precursor had good structure, morphology, and electrochemical performance.
