Implication

Experimental study demonstrates stable 4.5-volt operation in lithium metal full-cells using trace ethylene carbonate, suggesting a route to high-energy ether electrolytes.

Key Points

To evaluate the stabilization and solubilization effects of trace ethylene carbonate in low-concentration ether-based electrolytes for high-voltage lithium metal batteries.
Formulated a low-concentration ether-based electrolyte modified with trace additions of ethylene carbonate solvent.
Assembled and evaluated an 80 μm Li || LiNi0.8Co0.1Mn0.1O2 full-cell operating at an upper cutoff voltage of 4.5 V.
Identified that trace ethylene carbonate alters molecule-ion interactions, generating pronounced solubilization and stabilization effects in the ether electrolyte.
Achieved stable 4.5 V electrochemical cycling in 80 μm Li || LiNi0.8Co0.1Mn0.1O2 full-cells without premature electrolyte decomposition.
