Industrial Applications of Li difluorophosphate
| Industry | Application | Process |
|---|---|---|
| Lithium-ion batteries | Used as an electrolyte additive to enhance high-temperature performance and cycle life, and to improve interfacial stability | Added at low concentration (typically 0.5–2%) into the electrolyte, in combination with lithium salts (e.g., LiPF₆) and organic solvents |
| Electronic materials | Used in the synthesis of other functional materials or as a surface treatment agent | Employed in chemical reactions to prepare target products or applied as a coating on material surfaces |
Manufacturing Quality Control of Li difluorophosphate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (LiPO2F2 content) | Acid-Base Titration with Standardized NaOH | Hydrolysis of LiPO2F2 releases HF, which is titrated with standardized NaOH using phenolphthalein indicator. |
| Moisture Content | Karl Fischer Coulometric Titration | Electrochemical generation and reaction of iodine with water in anhydrous methanol-based reagent. |
| Fluoride Ion (F-) | Ion-Selective Electrode (ISE) Potentiometry | Measurement of potential difference across a fluoride-selective membrane relative to a reference electrode. |
| Phosphate Impurities (e.g., H3PO4, LiH2PO4) | Ion Chromatography (IC) with Conductivity Detection | Separation of anions on anion-exchange column followed by quantitative detection via conductivity. |
| Lithium Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Atomization and excitation of lithium atoms in high-temperature plasma; emission intensity at 670.78 nm measured. |
| Heavy Metals (Pb, Cd, Cr, Ni, Fe) | ICP-OES or ICP-MS | Multi-element quantification after acid digestion by measuring characteristic elemental emission (ICP-OES) or mass-to-charge ratios (ICP-MS). |
| Chloride Ion (Cl-) | Potentiometric Titration with AgNO3 | Titration with silver nitrate using silver indicator electrode; endpoint detected by abrupt potential change. |
| Sulfate Ion (SO42-) | Gravimetric Analysis as BaSO4 | Precipitation of sulfate as barium sulfate under controlled pH and temperature, followed by weighing. |
| pH of Aqueous Solution (1% w/w) | pH Meter Measurement | Direct potentiometric measurement using calibrated glass electrode in aqueous suspension. |
| Residue on Ignition | Gravimetric Analysis after High-Temperature Ashing | Heating sample at 550-600 C to oxidize organic impurities; residue weight expressed as % of original sample. |
| Particle Size Distribution | Laser Diffraction Particle Size Analysis | Analysis of angular scattering pattern of laser beam passing through dispersed sample to calculate size distribution. |
| Organic Volatile Impurities | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation by capillary GC column followed by identification and quantification via electron ionization mass spectrometry. |
