III. Core Application Fields
1.Lithium-Ion Battery Electrolyte
1.As a core solvent for electrolytes, it enhances battery energy density (cycle life ≥2000 cycles) and low-temperature performance (stable operation at -40°C), compatible with NCM/NCA/LFP systems.
2.Power battery electrolyte formulations, low-temperature lithium battery solvent supplier
2.Specialty Solvents
1.Replaces traditional benzene-based solvents, used in fragrance synthesis (ester extraction), pharmaceutical intermediate purification, eco-friendly coatings, and resin dissolution (VOC emissions reduced by 30%).
2.Pharmaceutical-grade carbonate solvents, eco-friendly resin dissolution solutions
3.Electronic Industry
1.: As an additive for capacitor electrolytes, improves the voltage resistance of MLCC/aluminum electrolytic capacitors (breakdown voltage ≥450V).
2.: Specialized solvents for high-precision electronic components, EMC electrolyte custom development
IVTechnical Advantages Module:
·Low-Temperature Performance: Through molecular structure optimization, EMC maintains electrolyte fluidity at -40°C, solving the winter range attenuation problem of new energy vehicles.
·Safety: Closed cup flash point of 23°C, combined with flame retardant additives, meets UL1642 battery safety standards.
Industry Data Reference:
·According to Boyan Consulting statistics, China's EMC market size will reach 18 billion RMB by 2025, with the power battery sector accounting for over 60%.
·Validates the critical role of EMC in long-cycle battery systems.
