Vinylene Carbonate (VC), Battery Grade 500g

Chemical Name: Vinylene Carbonate
CAS Number: 872-36-6
Product Code: EL872-36-6
Grade: Battery Grade
Brand: Xnergy

Product Introduction

Vinylene carbonate (VC) is one of the earliest and most extensively studied SEI-forming additives in lithium-ion battery research. VC undergoes reductive polymerization on the graphite anode surface at approximately 1.4 V vs. Li/Li⁺, depositing a thin, elastic poly(VC) film that passivates the electrode and suppresses continued electrolyte decomposition. Widely used at 0.5–2 wt% in commercial electrolyte formulations, VC has a decades-long track record of extending cycle life and reducing gassing in graphite-based cells. Xnergy supplies VC to battery-grade purity for both fundamental research and applied electrolyte development.

Key Features

• Reductive polymerization — forms a thin, coherent poly(VC) SEI film that passivates the graphite anode surface
• Early decomposition potential (~1.4 V vs. Li/Li⁺) — establishes protective film before major carbonate solvent breakdown
• Proven at low concentrations — effective at 0.5–2 wt%, minimizing impact on bulk electrolyte conductivity
• Reduced gassing — poly(VC) SEI suppresses CO₂ and CO generation from EC decomposition
• Purity ≥99% / H₂O ≤10 ppm — controlled quality for reproducible additive effect studies
• Flexible volumes — available from 1 kg for laboratory R&D to larger quantities for production
