Layered LiNi1/3Co1/3Mn1/3O2 was synthesized by a citric acid assisted solid-state method. The structure and electrochemical properties of the LiNi1/3Co1/3Mn1/3O2 materials were investigated. XRD analysis indicated the as-synthesized LiNi1/3Co1/3Mn1/3O2 was with the layered 𝛼-NaFeO2 structure. The discharge capacity was about 154 m.Ahg-1 at 0.1 °C rate in the range of 2.0–4.5 V. The kinetics of the LiNi1/3Co1/3Mn1/3O2 materials was investigated by the galvanostatic intermittent titration technique (GITT) method. The lithium ion diffusion coefficient of the LiNi1/3Co1/3Mn1/3O2 was determined in the range of 10-8−10-9 cm2.s-1 as a function of voltage of 3.7−4.5 V.
