Abstract
Li2Mn1-xVxO3 (0 ≤ x ≤ 0.018) samples were synthesized at low temperature by solid-state reaction using precipitated products of Mn and V. Li2Mn1-xVxO3 samples had a single phase of monoclinic layered structure with a space group of C2/m, and the solubility limit of V was 1.8%. Compared to Li2MnO3 sample, V-doped samples exhibited improved electrochemical properties. The initial charge and discharge capacities of Li1.682Mn0.982V0.018O3 sample were 353 and 248 mAh/g, respectively
Keywords: Lithium-ion batteries, Cathode material, Li2MnO3, Crystal structure, Electrochemical properties.
