Abstract
LiNi0.5Mn1.5O4 cathodes were synthesized by three different raw materials at high temperature. The samples were characterized by X-ray diffraction and scanning electron microscopy tests, respectively. The results indicate that the synthesized samples show pure spinel structure, and the samples synthesized by nickel–manganese hydrate and nickel–manganese oxide show regular geometrical shape. The electrochemical performance of sample synthesized by nickel–manganese oxide is best. The first discharge capacity is 141 mAh/g, and the capacity retention is 98.6% after 50 cycles at 0.5 C rate. The discharge capacity at 5 C rate is still 120 mAh/g. Better crystallization, smaller specific surface area, and lower polarization may be responsible for the excellent electrochemical performance of the LiNi0.5Mn1.5O4.
