Corrosion Resistance of Current Collector Materials in Bisamide Based Electrolyte for Magnesium Batteries

The compatibility of Ti, Cr, Ni, Fe, Al, steel type 304, Inconel 625, Hastelloy B and carbon coated current collectors with bisamide based electrolyte for Mg-batteries was investigated. Pitting corrosion of current collectors made from 3d-transition metals and steel type 304 was observed at potentials between 2.2-3.1 V vs. Mg/Mg2+. Anodic stability up to 3.8 V and resistance against corrosion for 48 h at a potential of 2.5 V vs. Mg/Mg2+ and above was found for Inconel 625, Hastelloy B, graphite and carbon coated Al foil.
