The rechargeable magnesium ion battery: An investigation of possible electrolytes The rechargeable magnesium battery has the potential of replacing lithium ion batteries in the area of electromobility. In contrast to lithium, the electrochemical deposition and dissolution of magnesium is not plagued by dendrite formation. The high volumetric capacity of 3832 mAh/cm3 (lithium: 2062 mAh/cm3) in conjunction with an optimized electrolyte and a suitable cathode can thus be exploited to built a magnesium battery with an energy density of up to 500 Wh/kg (lithium: up to 300 Wh/kg). Such a battery would make electrically driven vehicles highly attractive. Due to its lower reactivity compared to lithium, magnesium offers higher safety in technical applications. It is much more abundant and also more environmentally benign than lithium. |
