| Abstract: | TheLiLi Ni1/33Co1/3Mn1/3]O2 cathode materials were prepared by co-precipitation method using NH3· H2O as chelator and NaOH as precipitant. The research of electrochemical performance of Li Ni1/3Co1/3Mn1/3]O2 was developed by changing the addition manner and the content of ammonium hydroxide. The structure and surface shape were characterized by XRD and SEM. The lithiumon batteries were prepared with LiLiNi1/3Co1/3Mn1/3]O2 cathode material and the battery performances were studied.The results show that LiLiNi1/3Co1/3Mn1/3]O2 cathode material exhibits typical a-NaFeO2 structure; the distribution of sphere-like particle diameter is good. |
