To create an alternative battery system with regard to lithium-ion technology the development of an efficient and rechargeable 3 V Magnesium-Ion battery is envisaged in order to contribute to the enhancement of safety, rate capability und environmental sustainability of energy storage systems.

Keyfactors such as anode, cathode and electrolyte are in the research focus to realize the ambitious goals of this 3 V light metal energy storage system. On the one hand the optimization of the metallic Magnesium anode concerning a highly reversible Mg-deposition and dissolution is imperative. Therefore, the improvement of a non-aqueous electrolyte system is required that is compatible with the cathode in further consequence. Moreover, the synthesis of a new cathode material is of fundamental importance to enable a 3 V Magnesium-Ion battery system in general. In comparison to Lithium systems it is possible to develop Mg-batteries with an exceedingly high energy density (~ 500 Wh/kg vs. ~ 300 Wh/kg for Li) with significantly less expensive costs for the fabrication of Magnesium metal anodes by a factor of 24.
