Introduction | rubidium dihydrogen phosphate can be used as an acid binding agent to prepare bisfluorosulfonyl imide salts. Bis (fluorosulfonyl) imide salt, especially lithium bis (fluorosulfonyl) imide salt, because of its large anionic structure, fluoride ion has strong electric absorption, so that its binding force with cation is very weak, it can be used as a lithium electrolyte in lithium secondary batteries because of its high free nature of lithium ions in the molten state or in the presence of organic solvents, it can be used for super capacitor and aluminum electrolytic capacitor, and can also be used as Lewis acid catalyst, which has important industrial production value. |
