【Abstract】 LiNi_0.5Mn_0.5O₂ nanoparticles as cathode material for lithium ion battery have been successfully synthesized through a sol-gel method, and characterized by X-ray powder diffraction （XRD）, transmission electron microscopy （TEM）, scanning electron microscopy （SEM）. Electrochemical tests show that it delivers a large discharge capacity of 159.8 mA h·g^-1 vs. Li metal at 0.1 mA·cm^-2with voltage window of 2.5-4.5 V.更多还原
