LiNi1-x-yCoxMnyO2 cathode material have attracted much attention as promising alternative cathode materials due to their high capacity and good cycling stability. Understanding and control of interfacial phenomena between cathode materials and liquid electrolytes are of scientific importance for reinforcing development of high-performance lithium ion batteries. Polyaniline(PANI) is one of the promising materials because of its high electronic conductivity and good electrochemical stability. We aim to hybrid materials of the LiNi0.7Co0.15Mn0.15O2 Ni- rich phase combined with a conductive polymer PANI. Electrochemical properties and charge-discharge capability of PANI-coated LiNi0.7Co0.15Mn0.15O2 cathode materials were analyzed by scanning electron microscopy(SEM), transmission electron microscopy(TEM), thermo gravimetric analyzer(TGA), impedance measurements and charge discharge tests. |
