vinylene carbonate (CAS 872-36-6)
Nova International supplies Vinylene Carbonate with highest purity (CAS: 872-36-6, C3H2O3). This crucial material is used as a functional electrolyte additive and important in the lithium-ion batteries ( LIB). Vinylene carbonate can form stable robust SEI layer on graphitic anode thus inhibiting decomposition of electrolyte, reducing gassing and raising thermal stability etc., in short extend cycle life of rechargeable batteries greatly.

Key Features of vinylene carbonate
Superior SEI Formation
Efficiently polymerizes on the graphite anode surface to create a film that minimizes capacity loss during initial charge-discharge cycles.
Extended Battery Cycle Life
Greatly suppresses continuous side reactions among electrolyte and electrodes, thereby extending the overall cycle life of the battery.
Enhanced Thermal & High-Voltage Stability
Improves the structural resilience of the interphase under elevated operating temperatures and higher operating voltages.
Gassing Prevention Suppression
The technology helps curb gas build-up inside the lithium-ion cell, thus minimizing expansion or swelling of the cells. This will lead to greater safety and integrity of the cells.
High Purity & Low Moisture
Purified to ultra low moisture levels (20 ppm) resulting in no interference to highly sensitive electrochemical cells.
Flexible Industrial Compatibility
Seamlessly blends with standard carbonate-based solvents such as EC, DEC, DMC, and EMC for a range of cell chemistries.
FAQs
Nova International’s Vinylene Carbonate product is a performance-increasing electrolyte additive that can be added to lithium-ion batteries in EVs, ESS and electronics for battery lifetime extension.
When Vinylene Carbonate undergoes charging for the first time, it is the one which is preferred to react to generate an SEI (Solid Electrolyte Interphase) on the anode that is smooth and intact, hence it avoids the side reactions of other electrolytes, and helps preserve the active lithium ions.
Considering the melt point (19C-22C) and easy reacting to the moisture, it must be kept under strict tight sealed water-tight containers with dryness, and dryness, away from light, the light, the light and the moisture.
Absolutely, Nova International can package battery grade Vinylene Carbonate into custom sizes – including in lab scale bottles as well as in larger drums in order to meet your manufacturing demands.
