Abstract
Cathode material of LiNi0.4Co0.2Mn0.4O2 was prepared by mixed hydroxide or rheological reaction method at 850 degrees C within 15 h. The materials were characterized by XRD with Rietveld refinement, SEM, TG-DSC and electrochemical tests. The results showed that it has R-3m layered structure, with a high capacity and good thermal property. It delivered a specific capacity as high a's 208.7 mA (.) h/g(2.0-4.6 V, 0.1 C) Phase change of LixNi0.4Co0.2Mn0.4O2(0 < x < 1) in charge-discharge process will affect the cyclic stability of the materials, especially in the first 10 circles.
