Since they were introduced in the 1990s, lithium-ion batteries have become the batteries of choice for consumer electronics, being widely used in laptop computers, camcorders, and any applications where reliable batteries are needed. They are also being used in electric cars and hybrid motor vehicles.
One of the challenges in building a lithium-ion battery is that the electrolyte must be stable. Vinylene carbonate is an important additive that increases the stability of lithium-ion batteries.
An issue that surfaces with using vinylene carbonate in batteries is that it is often contaminated with halogens, which degrade battery performance.
For the vinylene carbonate used for lithium-ion batteries, LANXESS has developed a chemical vapor process which involves an innovative cleansing stage removing halogen contamination from the vinylene carbonate, resulting in a purity of 99.99 percent. This improves the electrochemical performance of the lithium-ion battery significantly.
