摘要：
LiNi0.5Mn1.5O4 compounds were prepared through a solid-state reaction using various Ni precursors. The effect of the precursorson the electrochemical performance of LiNi0.5Mn1.5O4 was investigated. LiNi0.5Mn1.5O4 made from Ni(NO3)2•6H2O shows the bestcharge-discharge performance. The reversible capacity of LiNi0.5Mn1.5O4 is about 145mAh g–1 and remained at 143mAh g–1 after10 cycles at 3.0 to 5.0 V. The XRD results showed that the precursors and dispersion method had significant effects on theirstructures. Pure spinel phase can be obtained wi...
