Polymer-in-"quasi-ionic liquid" electrolytes for high-voltage lithium metal batteries

Journal Article · · Advanced Energy Materials
Due to the limited oxidation stability (< 4 V) of ether oxygen, PEO-based polymer electrolytes are not compatible with high-voltage (> 4 V) cathodes, restricting the energy density of lithium (Li) metal batteries. Here, we design a new type of polymer in quasi-ionic liquid electrolyte (PQILE) that reduces the lone electron pairs of ether oxygens from PEO and ether solvent, induces the formation of stable interfacial layers on both surfaces of LiNi1/3Mn1/3Co1/3O2 cathode and Li metal anode, resulting in a capacity retention of 88.4%, 86.7% and 79.2% after 300 cycles with the charge cutoff voltage of 4.2, 4.3 and 4.4 V, respectively. It’s promising to use quasi-ionic liquids to design new polymer electrolytes for high-voltage and high-specific-energy Li metal batteries.
