Trace ethylene carbonate-mediated low-concentration ether-based electrolytes for high-voltage lithium metal batteries

A solubilization and stabilization effect of trace ethylene carbonate solvent assisted by the varied molecule-ion interaction was discovered in ether-based electrolyte, enabling the 80 μm Li || LiNi 0.8 Co 0.1 Mn 0.1 O 2 full-cell operate at 4.5 V stably.
