Abstract

To improve the cyclic stability at high temperature and thermal stability, the spherical Al₂O₃-modified Li(Ni_0.5Co_0.2Mn_0.3)O₂ was synthesized by a modified co-precipitation method, and the physical and electrochemical properties were studied. The TEM images showed that Li(Ni_0.5Co_0.2Mn_0.3)O₂ was modified successfully with nano-Al₂O₃. The discharge capacity retention of Al₂O₃-modified Li(Ni_0.5Co_0.2Mn_0.3)O₂ maintained about 99% after 200 cycles at high temperature (55 °C), while that of the bare one was only 86%. Also, unlike bare Li(Ni_0.5Co_0.2Mn_0.3)O₂, the Al₂O₃-modified material cathode exhibited good thermal stability.
