By means of an electrostatic spray deposition technique, thin-films (0.5 μm thick) of LiMxMn2-xO4 (M = Ni, Co) were fabricated on gold substrates. The prepared thin-films had a spinel-related structure. Cyclic voltammetry (CV) measurements were performed in a potential range of 3.4-5.5 V vs. Li/Li+. Both LiNixMn 2-xO4 and LiCoxMn2-xO4 exhibited reversible CV peaks at higher than 4.5 V. LiNixMn 2-xO4 showed two peaks at 4.7 V, and those corresponded to the redox of Ni2+ /4+ in the spinel structure, while the redox of Mn3+ /4+ took place at 4 V. Similarly, LiCoxMn 2-xO4 displayed current responses at 5 V due to the redox of Co3+ /4+.
