2. Storage and Usage Precautions
2.1 Storage Conditions
- Sealed, moisture-proof, and light-proof storage;
- Recommended storage in dry argon/nitrogen environment (relative humidity ≤30%, temperature 15~30℃);
- Secondary packaging with aluminum-plastic vacuum bags is recommended for long-term storage.
2.2 Usage Environment
- Operation in a dry room with dew point ≤-40℃ or inert gas glove box is recommended;
- Avoid moisture absorption (moisture can cause HF generation, corrode equipment and affect battery performance).
2.3 Operational Protection
- Wear protective gloves, goggles and lab coat during operation;
- Avoid direct skin contact or inhalation of dust;
- If contact with skin occurs, rinse immediately with plenty of water and seek professional medical advice.
2.4 Waste Disposal
- Classified disposal in accordance with local hazardous chemical disposal regulations;
- Do not discharge directly into sewers or natural water bodies.
3. Scientific Research Application Scenarios
- Electrolyte Formulation Optimization: Improve high-temperature cycle stability and low-temperature rate performance of batteries;
- Electrode Interface Regulation: Inhibit positive electrode oxygen evolution and negative electrode lithium dendrite growth, improve the stability of SEI/CEI films;
- Solid Electrolyte Modification: Enhance ionic conductivity and interface compatibility of solid electrolytes.
