Implication

Laboratory study demonstrates enhanced lithium transport and stable lithium deposition in lithium-oxygen batteries, indicating a viable pathway toward high-performance energy storage.

Key Points

To improve the lithium-ion transport ability of bis(trifluoromethanesulfonyl)imide-based ionic liquid electrolytes and achieve stable, uniform lithium deposition in lithium-oxygen batteries.
Guided by the Sand formula, introduced hydrofluoroether (HFE) into bis(trifluoromethanesulfonyl)imide-based ionic liquid (TFSI-IL) electrolyte and optimized component ratios.
Regulated the lithium solvation environment by using HFE to slice the ionic aggregate network, transitioning Li(TFSI)2- ion pairs into ionic aggregate clusters.
Achieved robust lithium deposition with a Coulombic efficiency of approximately 97.5% at a cycling rate of 1 mA cm^-2.
Improved lithium-oxygen battery cycling stability, showing a minimal overpotential increase of 64 mV after 75 cycles.
