Abstract
The electrochemical insertion of divalent magnesium cations into orthorhombic molybdenum(VI) oxide was studied with regard to their use as electroactive species in ion-transfer battery systems and compared to the insertion of Li{sup +} and Na{sup +}. Specific charges of up to 300 and 240 Ah kg{sup -1} were obtained in organic, propylene carbonate-based electrolytes for the lithium and sodium insertion, respectively, in the first reduction half-cycle. Reversible Mg{sup 2+} insertion could be demonstrated in a room temperature molten salt electrolyte consisting of 3 wt.% MgCl{sub 2}, 41 wt.% 1-ethyl-3-methylimidazolium chloride, and 56 wt.% AlCl{sub 3}. Specific charges of up to 160 Ah kg{sup -1} were obtained with MoO{sub 3} in the first reduction half-cycle. The Mg{sup 2+} insertion process can be enhanced using an organic electrolyte with traces of H{sub 2}O. In 1 M Mg(ClO{sub 4}){sub 2}/acetonitrile with 3 mol% of H{sub 2}O, specific charges of up to 210 Ah kg{sup -1} were measured in the first reduction. (orig.)
