Description

Vinylene Carbonate is a high-purity, cyclic carbonate ester that serves as a critical electrolyte additive and versatile chemical intermediate. Its primary commercial value lies in its ability to form a stable, protective solid electrolyte interface (SEI) layer on electrode surfaces, significantly enhancing the performance and longevity of advanced lithium-ion batteries. This compound is therefore essential for manufacturers in the energy storage, electric vehicle (EV), and consumer electronics sectors, as well as for fine chemical synthesis requiring a reactive vinylene building block.

Application

• Lithium-ion Battery Electrolyte Additive: Used as a key film-forming additive to improve cycle life, thermal stability, and high-voltage performance of batteries.
• Electric Vehicle (EV) Battery Packs: Incorporated into electrolyte formulations for next-generation EV batteries to enhance safety and energy density.
• Consumer Electronics Batteries: Employed in high-performance batteries for smartphones, laptops, and tablets for improved durability.
• Polymer and Resin Modification: Acts as a monomer or cross-linking agent in the synthesis of specialty polymers.
• Organic Synthesis Intermediate: Serves as a precursor for various pharmaceuticals, agrochemicals, and fine chemicals due to its reactive double bond and carbonate group.
• Supercapacitor and Energy Storage Research: Utilized in developing advanced electrolyte systems for other energy storage devices.

Quality Control

Our Vinylene Carbonate is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity, which is critical for battery performance. Quality is verified through advanced analytical techniques including Gas Chromatography (GC) and Karl Fischer titration. A comprehensive Certificate of Analysis (COA) detailing purity, moisture content, and key impurity profiles is provided with each shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is moisture-sensitive (hygroscopic) and should be kept under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation and polymerization.
