일반 설명

Anhydrous vinylene carbonate (VC) is a clear, colorless liquid with a relatively high boiling point of 162 °C. It is a highly polar solvent that is commonly used in a variety of chemical reactions and processes because it is an excellent solvent for a variety of organic and inorganic compounds. Electrochemically, VC decomposes at low anodic potentials on lithium metal anodes, forming polymeric species that often yield a desirable solid-electrolyte interphase.

애플리케이션

Alkyl carbonates such as VC are frequently employed as solvents for lithium ion battery electrolytes. The use of high-purity battery grade electrolytes with minimal water (<10 ppm) and acid (<10 ppm) content is crucial for achieving optimal electrochemical performance in these batteries. VC is electrochemically active and decomposes at low anodic potentials on lithium metal anodes, forming polymeric species that often yield a desirable solid-electrolyte interphase. Therefore, it is commonly used as a co-solvent with other carbonate solvents, such as ethylene carbonate and propylene carbonate, in lithium-ion battery electrolyte formulations to improve the performance and stability of the battery.

Dr. Schmuch, Dr. Siozios, Professor Dr. Winter, and Dr. Placke review the challenges and opportunities of nickelrich layered oxide cathode materials. They discuss production processes for the layered oxide cathode materials as well as their chemistry and morphology.

Due to the adverse impact of the continued use of fossil fuels on the earth’s environment and climate, researchers have been asked to develop new approaches for producing power using renewable sources like wind and solar energy

Here, we present a short review of ionic liquid electrolytes used in state-of-the-art rechargeable batteries including high performance and low-cost aluminum batteries, non-flammable Li-based batteries, and high-cycling and stable dual-graphite batteries. We also outline the key issues explored so as to identify the future direction of IL development.
