Useful:

• Canonical SMILES: CCOC(=O)OC
• Uses: Non-aqueous solvent for Li-ion batteries 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. EMC is majorly utilized as a co-solvent in the nonaqueous electrolyte. It enhances the energy density and discharge capacity of lithium-ion batteries.
