Abstract

Molybdenum-doped layered Li[Ni_0.5+xMn_0.5-2xMo _x]O₂ materials were synthesized by an ultrasonic spray pyrolysis method. Single phase of Li[Ni_0.5+xMn _0.5-2xMo_x]O₂ could be prepared in 0 ≤ x ≤ 0.05 region. Structural and electrochemical properties of the Li[Ni _0.5+xMn_0.5-2xMo_x]O₂ were characterized by means of X-ray diffraction, Rietveld refinements, and galvanostatic charge/discharge test. The discharge capacity increased linearly with the increase of molybdenum contents, x, and exhibited a high discharge capacity over 175 mAh/g between 2.8 and 4.4 V with a good capacity retention.
