摘要：
Pure LiNi0.5Mn1.5O4 phase was prepared by one-step solid-state reaction at 600 degrees C in air. TG measurement revealed that the oxygen loss occurred when the mixed precursors were heated above 700 degrees C. X-ray diffraction (XRD) pattern and scanning electron microscopic (SEM) image indicated that LiNi0.5Mn1.5O4 has cubic spinel structure with small and homogeneous particles. Electrochemical test showed that the prepared LiNi0.5Mn1.5O4 delivered up to 138 mA h g(-1), and the capacity retained 128 mA h g(-1) after 30 cycles. (c) 2005 Elsevier B.V. All rights reserved.
