Appearance: Transparent colorless liquid (melting point >35ºC), crystalline solid at room temperature.
Application: Ethylene carbonate (EC) is a high-performance organic solvent that can dissolve various polymers. It can also be used as an organic intermediate, replacing in the ethoxylation reaction, and is the main raw material for the ester exchange production of dimethyl carbonate. It can also be used as a raw material for the synthesis of furazolidone, water glass slurry, fiber finishing agent, etc. Additionally, it is used in lithium battery electrolytes. Ethylene carbonate can also be used as an active intermediate for the production of lubricating oils and greases.
EC (ethylene carbonate) has a high film-forming potential on the negative electrode and plays a crucial role in the formation of the solid electrolyte interface (SEI) film on the graphite negative electrode surface. The SEI film has a significant impact on the performance of lithium-ion batteries. In lithium-ion batteries, energy storage and release are achieved through the insertion and extraction of lithium ions between lithium-containing transition metal oxides and lithium-poor graphite materials. The use of graphite materials in lithium-ion batteries relies on the formation of an ion-conductive and electron-insulating solid electrolyte interface (SEI) film on the graphite surface by the electrolyte. This protective film isolates the electrolyte with a reduction stability much lower than the lithium insertion potential from the graphite electrode, ensuring that the electrolyte does not undergo reduction analysis at the lithium insertion potential, allowing for reversible lithium ion insertion and extraction in the graphite material. Ethylene carbonate can undergo analysis at a slightly higher potential of around 0.7V to form a stable SEI film, thereby suppressing the analysis of the electrolyte at lower potentials and enabling normal lithium ion insertion and extraction in the graphite material. Therefore, EC (ethylene carbonate) has a crucial impact on the performance of lithium-ion batteries.
