Lithium-Ion Battery Electrolyte Additive Package

Product Specifications

Technical details and manufacturing context for Lithium-Ion Battery Electrolyte Additive Package

Definition

This product is a specialized chemical formulation comprising multiple functional additives designed to be mixed with base electrolytes in lithium-ion battery manufacturing. The additive package improves battery cycle life, thermal stability, and safety characteristics by modifying electrode-electrolyte interfaces and suppressing unwanted side reactions. It serves as a critical performance-enhancing component in B2B supply chains for battery producers seeking to meet specific application requirements. Industrial purchasers typically procure these additive packages in bulk quantities for integration into their electrolyte production processes.

The package includes materials such as vinylene carbonate, fluoroethylene carbonate, lithium difluoro(oxalato)borate, and succinonitrile. Key parameters for procurement and quality control include recommended concentration in the final electrolyte (1–5 wt%), moisture content (≤20 ppm per GB/T 6283), purity level (≥99.9% per GB/T 23636), density (1.1–1.3 g/cm³ per ASTM D4052), storage temperature (5–35 °C), pH value (5.5–7.5 per GB/T 9724), flash point (≥60 °C per ASTM D93), chloride content (≤5 ppm per GB/T 23942), sulfate content (≤10 ppm per GB/T 23942), appearance (colorless to light yellow, clear liquid without sediment), and shelf life (12 months under recommended storage).

These values are reference ranges for directory purposes; actual specifications must be confirmed with the legal manufacturer or supplier for the specific model or application. The listed standards are verification references, not certifications of compliance. Buyers should verify that the product meets their process requirements and applicable regulations.

Working Principle

Chemical compounds in the additive package selectively adsorb onto electrode surfaces, form protective solid-electrolyte interphase (SEI) layers, scavenge harmful impurities, and improve ionic conductivity to enhance overall battery performance. The SEI layer stabilizes the electrode-electrolyte interface, reducing side reactions and extending cycle life. Impurity scavenging prevents degradation of the electrolyte and electrodes. Improved ionic conductivity facilitates efficient charge transport, contributing to better rate capability and thermal stability.
