Alkyl sulfonamide-Li perfluorosulfonimide salt deep eutectic electrolytes (DEEs).
- class="label">•
The viscosity of the DEEs exceeds that of LiPF6/organic carbonates by factors ≥10.
- class="label">•
A room temperature conductivity akin to that of LiPF6/linear carbonate is achieved.
- class="label">•
Eutectics with LiTFSI display much higher thermal stability than those with LiFSI.
- class="label">•
Stable cycling with both negative and positive electrodes is demonstrated.
