This document details the purity and environmental constraints for ATOMFAIR LiTFSI electrolyte salt. The crystalline compound requires storage in an anhydrous atmosphere to prevent moisture uptake and maintain its specified free acid and metallic impurity limits.
- Moisture Sensitivity: Moisture content must remain below 150 ppm to prevent hydrolysis and degradation of the salt.
- Free Acid Control: Free acid levels must be maintained below 150 ppm to avoid decomposition and corrosion in battery applications.
- Purity Requirement: Purity must be ≥99.9% with tightly controlled trace metal impurities to ensure electrochemical stability.
- Insoluble Matter Limit: Insoluble matter must be below 500 ppm to prevent contamination in electrolyte solutions.
How does the 99.97% purity of ATOMFAIR LiTFSI influence its electrochemical stability window in high-voltage lithium battery applications?
The certified 99.97% purity with trace metals each below 2 ppm (Na 1.39 ppm, Fe 1.63 ppm, Mg 1.56 ppm, K 1.83 ppm) minimizes catalytic side reactions that can narrow the electrochemical window, supporting stable operation across wide potential ranges typical of high-voltage cathodes. This directly reduces the risk of electrolyte decomposition under demanding cycling conditions.
Can ATOMFAIR LiTFSI be directly incorporated into poly(ethylene oxide) (PEO) solid electrolytes without additional purification?
Yes. The as-received ATOMFAIR LiTFSI powder with 99.97% purity and moisture below 39 ppm integrates seamlessly into PEO-based solid polymer electrolytes without requiring pre-purification or extended drying, as confirmed by ICP-OES and Karl Fischer testing. This compatibility is explicitly validated for advanced solid-state architectures.
What quality control tests are performed on ATOMFAIR LiTFSI to ensure its moisture and impurity levels?
Each batch is validated by ICP-OES for trace metals and Karl Fischer titration for moisture, with typical results showing 38.53 ppm H2O, Na 1.39 ppm, Fe 1.63 ppm, Mg 1.56 ppm, K 1.83 ppm, Cl¯ <5 ppm, and SO4²¯ <10 ppm. These values fall well within the strict COA-certified specification limits for high-purity battery-grade electrolyte salt.
The ATOMFAIR LiTFSI salt delivers exceptional thermal stability and ultra-low moisture content (38.53 ppm) with 99.97% purity, making it highly suitable for advanced solid-state and high-temperature lithium battery electrolytes, though careful moisture-free handling and specialized formulation expertise are required.
Positive
- Exceptional thermal stability: Exhibits outstanding structural stability at elevated temperatures, reducing hazardous chemical dissociation risks in hot cells and enabling reliable performance in high-temperature battery applications.
- Ultra-high purity with low moisture: Typical purity of 99.97% and moisture content below 39 ppm minimize side reactions and ensure consistent ionic conductivity, as validated by ICP-OES and Karl Fischer titration.
Trade-offs
- Sensitive to atmospheric moisture: With a moisture specification of ≤150 ppm and typical values below 39 ppm, exposure to ambient humidity can rapidly degrade the salt's quality, necessitating storage and handling in dry or inert atmospheres.
- Requires advanced formulation expertise: Optimal performance is achieved in specialized electrolyte systems such as solid-state polymers or ionic liquids, limiting direct use to professional laboratories focused on next-generation lithium battery engineering.
