Introduction
Ethylene carbonate is an ester of ethylene glycol and carbonic acid. Ethylene carbonate is used as a polar solvent with a molecular dipole moment of 4.9 D, only 0.1 D lower than that of propylene carb onate. It can be used as a high permittivity component of electrolytes in lithium batteries.
