Abstract

Electrodes F 3000 Progress in Rechargeable Magnesium Battery Technology. -Mo6S8-nSen (n = 0, 1, 2) Chevrel phases are synthesized from Cu 2.5 Mo 6 S 8-n Se n nanomaterials from which Cu is leached in an oxygen containing acid aqueous solution. The precursors are prepared by heating MoS2, MoSe2, Mo, and Cu in stainless-steel cells at 900°C for 16 h. A partial substitution of sulfur by selenium in Mo6S8-nSen Chevrel phases enables to elaborate fast cathodes for rechargeable magnesium batteries in which phenomena such as charge (Mg 2+ ) trapping are avoided. The practical capacity of Mo 6 S 6 Se 2 cathodes is higher than that of Mo6S8 cathodes. In addition, new solutions prepared from phenyl-MgCl and AlCl3 etheral solutions allow highly reversible behavior of Mg electrodes and high conductivity. -(AURBACH*, D.; SURESH, G.
