Magnesium Electrodes (Disc, Sheet, Roll) with A Thickness of 0.05-0.1 mm for Mg-Ion Battery Anode, CMIBAME

Magnesium metal is a highly promising anode material for magnesium-ion batteries (MIBs). The round disc shape is suitable for coin cell assembly and testing in magnesium-ion battery application (especially for CR20XX coin cell), while the sheet and roll shape are more suitable for pouch and cylindrical cells. 

The main features of MIBs are shown below:

• The "Divalent" character enable one magnesium ion (Mg2+) carries two electrons, whereas lithium ion (Li+) only carries one. Theoretically, this allows for very high volumetric energy density.

• Dendrite-Free (mostly): Unlike lithium and zinc, magnesium tends to deposit much more smoothly during charging. It is naturally resistant to forming dendrites, which makes it inherently safer.

• Abundance: Magnesium is the 8th most abundant element in the Earth's crust, making it significantly cheaper and more sustainable than lithium
