摘要：
Through the crystal alignment research based on the magnetic properties of LiNixMnyCo1-( x+y)O2 such as magnetic susceptibility and related anisotropy, a crystal aligned LiNi0.6Mn0.2Co0.2O2 electrode is obtained, in which the (00l) plane is frequently oriented perpendicular to the surface of a current collector. The crystal aligned LiNi0.6Mn0.2Co0.2O2 electrode steadily exhibits low electrode polarization properties during the charge/discharge process in a lithium-ion battery, thus affording an improved capacity compared to a pristine LiNi0.6Mn0.2Co0.2O2 electrode. The aligned LiNi0.6Mn0.2Co0.2O2 electrode may have an appropriate structural nature for fast lithium-ion transport due to the oriented (00l) plane, and thus it contributes to enhancing the battery performance. This enhancement is analyzed in terms of various electrochemical theories and experiment results; thus, it is verified to occur because of the considerably fast lithium-ion transport in the aligned LiNi0.6Mn0.2Co0.2O2 electrode.
