The prospects associated with Mg anode and further developments of high-performance RMBs are proposed. Rechargeable magnesium batteries (RMBs) promise enormous potential as high-energy density energy storage devices due to the high theoretical specific capacity, abundant natural resources, safer and low-cost of metallic magnesium (Mg).
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.
The assembled magnesium battery presents satisfactory capacity retention, with 10% capacity loss after 20 full cycles at the current density of 50 mA g −1 based on the mass of LiFePO 4 (Fig. 4c), superior to the recent reported dual-salt polyvalent-metal storage battery 26.
They are a candidate for improvement on lithium-ion battery technologies in certain applications. Magnesium has a theoretical energy density per unit mass under half that of lithium (18.8 MJ/kg (~2205 mAh/g) vs. 42.3 MJ/kg), but a volumetric energy density around 50% higher (32.731 GJ/m 3 (3833 mAh/mL) vs. 22.569 GJ/m 3 (2046 mAh/mL).
The QSMB demonstrates an energy density of 264 W·hour kg −1, nearly five times higher than aqueous Mg-ion batteries and a voltage plateau (2.6 to 2.0 V), outperforming other Mg-ion batteries. In addition, it retains 90% of its capacity after 900 cycles at subzero temperatures (−22°C).
Its average discharge voltage is 2.1 V with stable discharge platform and good cycling life. The calculated energy density based on the two electrodes is high. These findings open another door to rechargeable magnesium batteries.
Secondary magnesium ion batteries involve the reversible flux of Mg ions. They are a candidate for improvement on lithium-ion battery technologies in certain applications. Magnesium has a theoretical energy density per unit mass under half that of lithium (18.8 MJ/kg (~2205 mAh/g) vs. 42.3 MJ/kg), but a volumetric energy density around 50% higher (32.731 GJ/m (3833 mAh/mL) vs. 22.569 GJ/m (2046 mAh/mL).
