What is Ethylene Carbonate-based Electrolytes for Rechargeable Lithium Batteries about?

The properties of new ethylene carbonate (EC)-based electrolytes have been examined in an effort to obtain an electrolyte solution of higher conductivity than EC/2-methyltetrahydrofuran(2-MeTHF) without suppressing the lithium (Li) cycling efficiency more than necessary. Three, linearstructured solvents (LSs) and four, ring-structured solvents (RSs) have been used as co-solvents of EC. LiAsF, is used as the electrolyte. Although modifying 2-MeTHF improves conductivity, no electrolyte system has a higher Li cycling efficiency than EC/2-MeTHF. Of the organic electrolytes examined in this work, the EC/2-MeTHF/THF ternary mixed solvent system shows approximately 50% higher conductivity and the highest Li cycling efficiency, with a value 1.2% lower than EC/2-MeTHF. Since our results were only obtained from lithium half-cell tests, future applications and cathode compatibilities must be thoroughly examined.
