[BULK] Ternary electrolyte Nickel-Cobalt-Aluminum Nickel-Cobalt-Manganese Electrolyte

2KG – 100KG.

Ternary cathode materials such as NCM811, NCM622, NCM523, NCM111, and NCA typically use organic carbonate-based electrolytes containing a lithium salt. The standard composition includes:

• Solvent system: A mixture of EC (ethylene carbonate), EMC (ethyl methyl carbonate), and DMC (dimethyl carbonate), offering high dielectric constant and good ionic conductivity;

• Lithium salt: LiPF₆ (lithium hexafluorophosphate), widely used as the lithium source;

• Additives: VC (vinylene carbonate), FEC (fluoroethylene carbonate), phosphate esters, etc., to enhance interfacial stability, especially under high voltage operation.

Key Functions:

• Maintain electrolyte oxidative stability at high voltages (>4.2V);

• Suppress side reactions on high-Ni cathode surfaces;

• Facilitate formation of stable SEI/CEI films;

• Improve rate performance and cycling life;

• Enhance thermal stability and overall battery safety.
