Magnesium batteries are one of the alternative technologies. Magnesium metal is an attractive anode due to the high abundance of magnesium and its volumetric capacity of 3833 mAh cm −3 and gravimetric capacity of 2205 mAh g −1 combined with a low redox potential (−2.37 V vs. SHE).
Different rechargeable magnesium battery configurations were assumed and their dependence of volumetric energy densities on gravimetric energy densities are provided assuming realistic conditions with optimized electrode thicknesses and loadings, electrode porosity and optimized electrolyte quantity.
Taking all together, the state of art results demonstrate that the development of a magnesium battery of species I is a very difficult target, as it requires electrolytes able to reconcile the “ Devil” (anode) with the “ Holy Water ” (cathode) electrochemistry.
Thus, with a properly designed electrolyte-cathode system, one can expect to obtain practical secondary magnesium batteries (RMB) with an energy density of at least 320 Wh kg −1 or 600 Wh L −1 ( Fig. 1 ).
A magnesium–air battery has a theoretical operating voltage of 3.1 V and energy density of 6.8 kWh/kg. General Electric produced a magnesium–air battery operating in neutral NaCl solution as early as the 1960s. The magnesium–air battery is a primary cell, but has the potential to be 'refuelable' by replacement of the anode and electrolyte.
However, the energy density of previously proposed rechargeable magnesium batteries is low, limited mainly by the cathode materials. Here, we present new design approaches for the cathode in order to realize a high-energy-density rechargeable magnesium battery system.
