Overview | manganese phosphate is a white lump or amorphous powder, rarely soluble in water or alcohol, soluble in acid; manganese phosphate (2) chemical formula MnPO4 · H2O, green gray non-crystalline powder. Because the potential of Mn3 /Mn2 is higher than that of Li /Li, the LiMnPO4/C composite material has the advantage of potential high energy density, |
Application | manganese phosphate is one of the raw materials for the synthesis of LiMnPO4/C composites, the electrical properties of the composites can be improved by changing the morphology and particle size of the manganese phosphate precursor. |
production method | Production Method 1: manganese sulfate and soda ash were heated and dissolved in water, the soda ash solution was then added to the manganese sulfate solution with sufficient stirring to produce manganese carbonate. The end point of the reaction was controlled to pH = 7.5-8, and the reaction was clarified by static standing. The Upper sodium sulfate supernatant was removed by suction, and then washed with distilled water. In the washed manganese carbonate precipitate, the mother liquor of manganese acid phosphate was added in portions and stirred until pH = 4. At this point, manganese phosphate was obtained. Process 2: When the Mn (II) salt solution reacts with sodium phosphate, white manganese phosphate (II) heptahydrate Mn3(PO4)2 · 7H2O is precipitated. |
