4-Vinyl-1,3-dioxolan-2-one

Product Overview

4-Vinyl-1,3-dioxolan-2-one, commonly known as Vinyl Ethylene Carbonate (VEC), represents a critical component in the formulation of modern energy storage systems. As a highly reactive organic carbonate derivative, this specialty chemical serves primarily as an electrolyte additive in lithium secondary batteries. Our manufacturing process ensures exceptional purity levels, making it an ideal choice for manufacturers seeking to enhance the safety and longevity of their battery products.

The unique chemical structure of VEC allows it to polymerize effectively on electrode surfaces. This property is leveraged to create a robust Solid Electrolyte Interphase (SEI) film, which is essential for preventing solvent co-intercalation and minimizing electrolyte decomposition during operation.

Industrial Applications

The primary application of 4-Vinyl-1,3-dioxolan-2-one is within the lithium-ion battery supply chain. When incorporated into electrolyte formulations, VEC offers several distinct performance advantages:

• Enhanced SEI Film Stability: Initiates decomposition at approximately 1.35V to form a dense protective layer on graphite anodes.
• Improved Safety Profile: Features a higher flash point and boiling point compared to standard carbonates, reducing thermal runaway risks.
• Superior Cycle Life: Significantly improves charge-discharge efficiency and retains discharge capacity over multiple cycles.
• Gas Suppression: Effectively reduces CO2 release during cycling, indicating stable electrode interface formation.

Technical testing demonstrates that adding optimized amounts of VEC can increase retained discharge capacity from 68.8% to 84.8% after extensive cycling. This makes it indispensable for high-performance consumer electronics and electric vehicle battery packs.

Quality Assurance and Packaging

As a global manufacturer, we prioritize product integrity from synthesis to delivery. Each drum is sealed to prevent moisture absorption, which is critical for maintaining electrochemical performance. We provide comprehensive Certificates of Analysis (COA) with every shipment. Standard packaging includes 20kg or 200kg drums, stored in cool, dry conditions away from direct sunlight.
