The electrodeposition of molybdenum in the binary alkali metal salts of bis[(tri-fluoromethyl)sulfony]amide LiTFSI-CsTFSI (eutectic point, 0.07: 0.93 in mole fraction; m.p., 112 oC) was investigated. Results show that MoCl3 was selected as the molybdenum ion source and electroreduced into metallic molybdenum on nickel plate in the eutectic LiTFSI-CsTFSI melt at 200 oC and 150 oC. Cyclic voltammetry measurement combined with SEM and XPS were employed. The results confirm that the electrodeposits obtained potentiostatically at 1.4 V (vs. Li+/Li) on nickel electrode are amorphous molybdenum
