Descrizione generale

Anhydrous ethyl methyl carbonate (EMC) is a clear, colorless liquid with a sweet, ether-like odor. It is a highly polar solvent with a moderate boiling point (101 °C) and relatively low vapor pressure, making it suitable for use in a wide range of chemical reactions and processes. EMC is an excellent solvent for many organic compounds including cellulose, ester, and amides, and it can dissolve a variety of inorganic compounds as well, including many electrolytic salts.

Applicazioni

Alkyl carbonates find applications as solvents for lithium ion battery electrolytes and the use of high quality battery grade electrolytes having extremely low water (<10 ppm) and acid (<10 ppm) contents are critical for achieving high electrochemical performance.

High-Energy Lithium-Ion Batteries via a Couette–Taylor-Flow-Reactor

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.

Nanostructured Olivine-based Cathode Materials for Lithium-ion Batteries

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

Ionic Liquids Based Electrolytes for Rechargeable Batteries

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.
