A robust Li deposition in TFSI-IL electrolyte is achieved through introducing hydrofluoroether to regulate the solvation environment of electrolyte to boost Li+ transport ability according to the Sand formula. The formation of sliced ionic aggregate leads to the improved transport parameters in Sand formula. The performance of Li-O2 battery is greatly improved thanks to the realized robust Li deposition behavior.
