Vinylene carbonate, CAS: 872-36-6

Key Applications:

1. Lithium‑Ion Battery Electrolytes

• Serves as a solid electrolyte interphase (SEI)–forming additive on graphite anodes, improving passivation and reducing irreversible capacity loss.
• Enhances cycle life, rate capability, and low‑temperature performance in Li‑ion cells.
• Reduces electrolyte decomposition and gas evolution under high‑voltage operation.

2. High‑Voltage Cathode Stabilization

• Improves interfacial stability for NMC, NCA, and other high‑voltage cathode chemistries.
• Mitigates transition‑metal dissolution and oxidative degradation at elevated potentials.

3. Silicon‑Based Anode Systems

• Essential for stabilizing Si and SiOx anodes, forming a flexible SEI that accommodates volume expansion.
• Enables higher‑capacity anode designs for next‑generation EV and consumer‑electronics batteries.

4. Lithium Metal and Lithium‑Ion Polymer Batteries

• Promotes formation of a dense, uniform SEI on lithium metal surfaces, reducing dendrite growth.
• Supports improved coulombic efficiency in rechargeable Li‑metal systems.

5. Sodium‑Ion and Potassium‑Ion Batteries

• Functions as a film‑forming additive in emerging Na‑ion and K‑ion electrolytes, improving interfacial stability and cycle retention.

6. Electrochemical Research & Mechanistic Studies

• Used as a model compound for studying SEI formation mechanisms, electrolyte decomposition pathways, and interfacial chemistry.
• Supports development of predictive models for electrolyte behavior under high‑voltage and high‑temperature conditions.
