prototype systems for rechargeable magnesium batteries - home battery system

The thermodynamic properties of magnesium make it a natural choice for rechargeable battery anode materials, as it may provide a much higher energy density than the lead-acid and nickel-cadmium systems commonly used.
In addition, magnesium is cheap, eco-friendly and safe to handle compared to lead and cadmium.
However, the development of Mg batteries has been hindered by two problems.
First of all, due to the chemical activity of Mg, only a solution that does not donate or accept protons is suitable as an electrolyte;
However, most of these solutions allow growth to inhibit the passive surface film of any electrochemical reaction 1,2, 3.
Second, the selection of cathode materials is limited by the difficulty of Mg ion insertion in many hosts4.
Following the previous Mg electrode in various non-
We have now developed a rechargeable Mg battery system that demonstrates the prospect of application.
These systems include an electrolyte solution based on Mg organic halogen aluminum salt and a MgxMo3S4 cathode, where Mg ions can be inserted reversibly and the dynamics are relatively fast.
We expect further increases in energy density to make these batteries a viable alternative to existing systems.
