Abstrak

A Li-rich Li[Li0.2Ni0.2Mn0.6]O2 cathode material coated with polyaniline (PANI) was prepared by a chemical in situ polymerization method. PANI is evenly coated on the surface of particles of the Li-rich material Li[Li0.2Ni0.2Mn0.6]O2 to form a good electrical conductive layer. The samples were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). When the PANI coating content was 6%, the Li-rich material exhibited a regular morphology and optimal electrochemical properties. The initial specific discharge capacity of the Li-rich material Li[Li0.2Ni0.2Mn0.6]O2/PANI was 262.0 mAh g-1 at 0.1 C, and that after 50 cycles was 243.7 mAh g-1, representing a capacity retention of 93% after 50 cycles.
