| Application: | Manganese(II) bromide can be used as: • A key component the development of highly efficient phosphorescent green-light-emitting diodes (PHOLEDs). • A precursor salt in the synthesis of manganese(II) bromide-based organic-inorganic hybrid materials for high-performance optoelectronic devices, particularly in the areas of green light-emitting diodes and UV photodetectors. • A key component in the synthesis of magnetic polaronic and bipolaronic excitons in Mn (II) doped (TDMP) PbBr4: The study investigates ferromagnetism in Mn doped semiconductors and highlights the special electronic properties of Mn-doped lead bromides (Huang et al., 2022). |
| General description: | Manganese(II) bromide is an ionic compound soluble in water and polar solvents. It can be used in rechargeable batteries, particularly in redox flow batteries, due to its ability to store and release electrical energy efficiently. Additionally, it is also used in dye-sensitized solar cells as an electrolyte, to facilitate the conversion of light into electrical energy. In flow fuel cell applications, MnBr2 serves as an electrolyte that facilitates the conversion of chemical energy into electrical energy. |
