摘要：
Effect of ball milling and electrolyte on the properties of high-voltage LiNi0.5Mn1.5O4 was investigated. Ball milling has significant effect on the synthesis and property of LiNi0.5Mn1.5O4. The X-ray diffraction(XRD) patterns indicate that LiNi0.5Mn1.5O4 can't be synthesized without ball milling even calcined at 900 degrees C. When synthesized with ball milling, LiNi0.5Mn1.5O4 almost exhibits only one plateau at around 4.7 V. With the increase of ball milling time, the capacity of LiNi0.5Mn1.5O4 increases, but the cycling performance is not highly affected. The electrochemical property of LiNi0.5Mn1.5O4 highly depends on the electrolyte. The stable and high-voltage-resistant electrolyte is much beneficial to enhancement of electrochemical property of LiNi0.5Mn1.5O4 such as coulombic efficiency and cycling performance.
