Application

The presence of electrolyte additives enhances the performance of lithium ion batteries by improving their thermal stability and ionic conductivity. Additives also reduce the flammability of electrolytes and provide overcharge protection. 2-Propynyl methanesulfonate finds application as additive in lithium ion batteries.

Preparation Note

  • These additives have low water content (less than 100 ppm), please handle under inert and moisture free environment (glove box).
  • Keep containers tightly closed.
  • Keep away from heat and ignition sources.
  • Store in a cool and dry place.
  • Avoid storing together with oxidizers.

Articles

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.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
