Lithium Pyrophosphate (Li4P2O7) | Battery Grade
Product Overview
Lithium Pyrophosphate (Li4P2O7) is a high-stability, white inorganic crystalline powder. In recent years, it has become a highly sought-after functional material in the advanced energy sector. It is exceptionally effective as a surface coating material for high-voltage battery cathodes and serves as a crucial building block in the development of next-generation solid-state electrolytes.
At Shandong Yinglang Chemical Co., Ltd., established in 2016, we supply High-Purity Lithium Pyrophosphate (≥ 99.5%) engineered specifically for battery material innovators and specialty glass manufacturers. By strictly limiting trace transition metals and moisture content, our product ensures superior electrochemical performance and prolonged cycle life for your energy storage systems.
Technical Specifications (COA)
For advanced battery applications, strict control over magnetic impurities is essential to prevent micro-short circuits. Typical specifications:
| Purity (Li4P2O7) | ≥ 99.5% |
|---|---|
| Lithium (Li) Content | ~ 13.5% |
| Moisture / Water | ≤ 0.5% |
| Iron (Fe) | ≤ 10 ppm |
| Copper (Cu) | ≤ 5 ppm |
Key Applications
- Cathode Surface Modification: Widely used as a protective coating layer on high-nickel NCM, NCA, and Lithium-Rich cathodes to suppress side reactions with liquid electrolytes.
- Solid-State Electrolytes: Acts as a vital precursor and structural component in the synthesis of phosphate-based solid electrolytes.
- Specialty Glass & Ceramics: Serves as a high-performance network former and flux in low-expansion ceramics and sealing glasses.
- Catalyst Support: Utilized as a stable matrix for specialized chemical catalysts in high-temperature environments.
🛡️ Maximizing Cathode Lifespan via Surface Coating
High-energy-density cathodes (like NCM811) often suffer from structural degradation and transition metal dissolution when in direct contact with organic liquid electrolytes at high voltages. Coating the cathode particles with our High-Purity Li4P2O7 creates a robust, lithium-ion conducting protective barrier. This drastically reduces interfacial side reactions, lowering internal resistance and significantly extending battery cycle life.
Packaging Options
To protect the high-purity powder from environmental contamination and moisture uptake:
- 25 KG Double-layer PE bags securely enclosed within UN-approved Fiber Drums.
- 25 KG Multi-wall Kraft paper bags with heavy-duty PE inner liners.
