Manufacturing Quality Control of Lithium sulfide
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Purity (Main Component Content) | Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | The sample is dissolved and the lithium content is measured using an ICP instrument, then the Li₂S purity is calculated based on stoichiometric relationships; offers high sensitivity and excellent accuracy. |
| Iodometric Titration | Sulfide ions (S²⁻) react with iodine in a redox reaction. The sulfur content is determined by titrating with a standard iodine solution, allowing calculation of Li₂S content; suitable for determining high concentrations of sulfides. | |
| Moisture Content | Karl Fischer Titration | Based on the quantitative reaction of iodine with sulfur dioxide in the presence of water, this method precisely measures trace moisture in samples. Available in coulometric and volumetric forms, it is suitable for moisture detection in inorganic solids. |
| Oxygen Content / Oxide Impurities | Inert Gas Fusion-Infrared Absorption Method (e.g., Oxygen/Nitrogen Analyzer) | The sample is melted in a high-temperature inert atmosphere, releasing oxygen which is then quantified by an infrared detector to assess levels of oxide impurities such as Li₂O. |
| Particle Size Distribution | Laser Diffraction Analysis (LDI) | The sample is dispersed in liquid or gas, and particle size distribution is determined based on laser light scattering. Used to ensure consistency in material physical properties. |
| Crystal Structure | X-ray Diffraction (XRD) | Analyzes crystal structure via diffraction patterns to confirm whether the sample is pure-phase Li₂S and detect any crystalline impurities (e.g., Li₂O, unreacted starting materials). |
| Surface Morphology | Scanning Electron Microscopy (SEM) | Observes particle morphology, size, agglomeration, and surface defects, helping evaluate synthesis process stability and material uniformity. |
| Impurity Elements | ICP-MS or GD-MS (Glow Discharge Mass Spectrometry) | High-sensitivity detection of metallic impurities (e.g., Fe, Cu, Ni, Na), ensuring high-purity requirements for battery-grade materials; GD-MS allows direct solid sample introduction. |
| Specific Surface Area | BET Surface Area Analysis | Determines specific surface area using nitrogen adsorption-desorption isotherms and the BET model, influencing material reactivity and storage stability. |
| Thermal Stability | Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC) | Monitors mass changes (TGA) and heat flow (DSC) under controlled temperature ramping to evaluate decomposition temperatures, volatiles, and phase transitions. |
