Vinylene carbonate is a product of high purity (min. 99.99%) with free chlorine content below 15 ppm. It is used mainly for the production of electrolytes for lithium-ion batteries (Li-Ion). It is also a raw material/intermediate in the organic synthesis of membrane materials.
Vinylene carbonate is of particular importance for the dynamically developing sector of Li-Ion batteries and accumulators. As a specialist additive for electrolytes, it promotes the creation of membranes in the process of film formation. Additives of this type improve stability by preventing the formation of dendrites and degradation of electrolyte solution.
Vinylene carbonate is an important product for the broadly understood consumer electronics industry, especially for the production of electrolytes for lithium-ion batteries (Li-Ion), where it is used as an additive promoting the formation of membranes and precursor for polymerisation.
Owing to the presence of unsaturated bonding in its structure the product can be also used in the polymerisation process to obtain membranes and protective and separating coatings, which is of crucial importance, e.g. in the production of capsule coatings (pharmaceutical industry) or fixing agents (colourant and pigment industry).
Vinylene carbonate is produced as a colourless clear liquid having a characteristic odour, stabilised by adding antioxidants and free radical scavengers (BHT 70-110 ppm) to avoid polymerisation.
Vinylene carbonate dissolves in ethanol, tetrahydrofuran, ethylene carbonate, propylene carbonate and dimethyl carbonate and diethyl carbonate (electrolytic solvents used in lithium-ion accumulators).
