3. Introduction to Magnesium ion batteries
Rechargeable batteries are essential for renewable energy and long-range
vehicle applications.
Greater abundance of Mg and lower cost than lithium.
Better theoretical performance, but some hindrances.
No dendrite formation, yet slower solid-state ionic diffusion (Liu et al., 2021)
4. Introduction……..
Mg is lighter than the other elements like lithium, previousely used in
batteries
Magnesium offers a higher volumetric energy density compared to lithium,
making it a credible alternative for next-generation storage systems.
the theoretical volumetric capacity of a magnesium-ion battery is
3833 mAh/mL, which nearly doubles the volumetric capacity of lithium
(2062 mAh/mL)
Intercalation agents such as phosphates, sulphides, and oxides contribute to
the energy density of magnesium. (Zhang et al., 2021)
5. Cathode materials for Mg ion batteries
Research on cathode materials for magnesium-ion batteries is ongoing, and various materials
are being explored for their potential as cathodes. Some of the possible cathode materials for
magnesium-ion batteries include:
Manganese dioxide (MnO2)
Vanadium pentoxide (V2O5)
Phosphates (e.g., MgFePO4F)
Sulfides (e.g., MgS)
Antimony sulfide (Sb2S3)
Titanium disulfide (TiS2)
Iron sulfides (e.g., FeS2)
Molybdenum disulfide (MoS2)
Prussian blue and its analogs
Organic cathode materials (Zhang et al., 2019, Esser et al., 2021)
6. Potential Organic materials
Possible organic cathode materials for magnesium-ion batteries include:
Anthraquinone derivatives, Terephthalate-based materials, Polycyclic
aromatic hydrocarbons and Prussian blue analogs
