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).
Both of these aspects make magnesium batteries a very attractive alternative for commercial development. With this new magnesium activation technique, the KIST researchers have demonstrated highly efficient magnesium cycling, marking an important step forward in the mass production of commercial magnesium batteries.
We designed a quasi-solid-state magnesium-ion battery (QSMB) that confines the hydrogen bond network for true multivalent metal ion storage. 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.
Third, magnesium also being lightweight provides a theoretical specific capacity of 2205 A h kg −1, making it an attractive high-energy density battery system.
With relatively low costs and a more robust supply chain than conventional lithium-ion batteries, magnesium batteries could power EVs and unlock more utility-scale energy storage, helping to shepherd more wind and solar energy into the grid. That depends on whether or not researchers can pick apart some of the technology obstacles in the way.
Magnesium-based batteries are one of these promising alternatives. Magnesium forms divalent ions (Mg 2+), whereas lithium ions are monovalent (Li +). As a result, magnesium has the potential to achieve extremely high energy densities. Indeed, a pure magnesium metal anode can deliver a volumetric capacity around 1.9 times larger than lithium metal.
