Ammonium dihydrogen phosphate Ammonium dihydrogen phosphate Ammonium dihydrogen phosphate (ADP), commonly called monoammonium phosphate (MAP) is a chemical compound with formula . It is a white crystalline solid consisting of ammonium cations and dihydrogen phosphate anions in equal proportions. ADP is a major ingredient of agricultural fertilizers and some fire extinguishers. It also has significant uses in optics and electronics. Monoammonium phosphate is soluble in water and crystallizes from it as the anhydrous salt in the tetragonal system, as elongated prisms or needles. It is practically insoluble in ethanol. Solid monoammonium phosphate can be considered stable in practice for temperatures up to 200
Lithium ion manganese oxide battery Lithium ion manganese oxide battery A Lithium ion manganese oxide battery is a lithium ion cell that uses manganese dioxide, , as the primary cathode material. They function through the same intercalation/de-intercalation mechanism as other commercialized secondary battery technologies, such as . They are a promising technology as their manganese-oxide components are earth-abundant, inexpensive, non-toxic, and provide better thermal stability. One of the more prominent compounds is , a lithium-manganese-oxide based material with a spinel structure (space group Fd3m). In addition to being a cheap and non-toxic alternative material, the spinel structure of provides a three-dimensional framework for the insertion
