Abstract

Spherical morphology layered Li[Ni_0.5Mn_0.5] _1-xCo_xO₂ (0≤x≤0.33) powders have been synthesized by ultrasonic spray pyrolysis method. Single phase of Li[Ni _0.5Mn_0.5]_1-xCo_xO₂ could be prepared in 0≤x≤0.33 region. Structural and electrochemical properties of the Li[Ni_0.5Mn_0.5]_1-xCo_xO ₂ materials were characterized by means of powder X-ray diffraction (XRD), Rietveld refinements, and galvanostatic charge/discharge test. The discharge capacity increased linearly with the increase of Co-substituted contents. Li[Ni_0.4Mn_0.4Co_0.2]O₂ electrode delivered a high discharge capacity over 175 mA h g^-1 between 2.8 and 4.4 V with a good capacity retention.
