Description

General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product is used as a greener reagent. Click here for more information.

Application

Diethyl carbonate finds application as solvent for lithium ion battery electrolytes.[1] 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.

Other Notes

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.
