Packaging and shipping
Ethyl Methyl Carbonate (EMC, CAS 623-53-0) is a high-purity, low-toxicity carbonate solvent widely used in the lithium-ion battery industry. It is a colorless transparent liquid with molecular formula C₄H₈O₃ and molecular weight 88.11. It features moderate viscosity, good electrochemical stability, and excellent compatibility with other carbonate solvents, making it an ideal component for high-performance battery electrolytes. Our EMC is mainly supplied as battery grade with purity up to 99.90%, strict impurity control, stable quality, and reliable supply to meet global industrial standards.
EMC is primarily used in lithium-ion battery electrolytes, where it improves battery cycle life, rate performance, and low-temperature stability when mixed with EC, PC, DEC and DMC. It also serves as a mild organic solvent in chemical synthesis and reaction systems. In application, it is blended evenly with other solvents under dry and airtight conditions. It is widely applied in consumer electronics, power batteries, and energy storage systems due to its stable performance, safe operation, and strong environmental adaptability.
Product Description
Ethyl Methyl Carbonate (EMC, CAS 623-53-0) is a high-purity, low-toxicity and environmentally friendly carbonate solvent, widely recognized as a key raw material for lithium-ion battery electrolytes.
It is a colorless transparent liquid with molecular formula C₄H₈O₃ and molecular weight 88.11.
It has moderate boiling point, low viscosity, good fluidity and high electrochemical stability, with strong compatibility with other carbonate solvents such as EC, DMC and DEC.
Our EMC is mainly produced as battery grade with purity above 99.90%, strict control of moisture and metal impurities, stable quality and consistent performance. Supported by a complete quality system and stable supply chain,
it fully meets international industrial requirements for advanced energy storage applications.
EMC is mainly used in lithium-ion battery electrolytes to improve overall battery performance, including cycle life, charging and discharging efficiency, and low-temperature adaptability.
It is usually mixed with other solvents in a certain ratio under dry and sealed conditions to form stable electrolyte solutions. It is widely applied in consumer electronics, new energy vehicles, energy storage batteries and other high-demand scenarios.
In addition, EMC can also be used as an efficient organic solvent in chemical synthesis and reaction processes, with mild properties and low volatility.
In actual use, it should be stored in a dry, ventilated and sealed environment to avoid moisture absorption. With stable performance and high safety, EMC has become an indispensable material in the modern new energy industry.
