Applications
1. For Lithium Battery Electrolytes: Ethylene carbonate (EC, CAS 96-49-1) is a key solvent in lithium-ion battery electrolytes, dissolving lithium salts such as LiPF6 and supporting stable ion transport, cycle performance and safety in high-energy battery cells.
2. For Electrolyte Formulations And Energy Storage: EC is a standard component in electrolyte blends for consumer electronics, electric vehicles and grid storage applications, supporting formulation stability and high dielectric solvation when combined with linear carbonate co-solvents.
3. For Green And Polar Solvent Applications: As a highly polar cyclic carbonate, EC dissolves a wide range of polymers and electrolytes, making it a useful green solvent in coatings, surface cleaning and polymer processing applications.
4. For Chemical Intermediate And Derivatives: Ethylene carbonate is a versatile intermediate for producing dimethyl carbonate, ethylene glycol and other carbonate derivatives, and serves as an active intermediate in lubricant and fiber treatment formulations.
5. Reliable Supply For Global Industry: Supplied in high-purity battery-grade and industrial-grade forms with consistent quality, ethylene carbonate gives battery, chemical and coatings manufacturers a dependable cyclic carbonate with stable supply, flexible packaging and professional technical support.
Quality Assurance
Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.
Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
