Synthesis of high power type LiMn1.5Ni0.5O4 by optimizing its preparation conditions

LiMn1.5Ni0.5O4 has been synthesized by an ultrasonic-assisted sol–gel method. The precursor is heat treated at a series of temperatures from 650 °C to 1000 °C. The structure and physical–chemical properties of the as-prepared powder are investigated by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), cyclic voltammetry (CV) thermal gravimetric and galvanostatic charge–discharge tests in detail. As temperature goes up, the...
