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.
