“…With respect to the utilization of lithium metal, ILbased electrolytes offer an additional major advantage, since they show a significantly improved cycling performance of the lithium electrode as compared with conventional Li-ion electrolytes, especially when incorporating PYR 14 + paired with TFSI − and incorporated [29,30] or not [31] in solid polymer electrolytes (SPEs) or paired with FSI − for lower temperature applications [32,33].

The Li-O 2 battery has been attracting much attention recently, due to its very high theoretical capacity compared with Li-ion chemistries. Nevertheless, several studies within the last few years revealed that Li-ion derived electrolytes based on alkyl carbonate solvents, which have been commonly used in the last 27 years, are irreversibly consumed at the O 2 electrode. Accordingly, more stable electrolytes are required capable to operate with both the Li metal anode and the O 2 cathode. Thus, due to their favorable properties such as non volatility, chemical inertia, and favorable behavior toward the Li metal electrode, ionic liquid-based electrolytes have gathered increasing attention from the scientific community for its application in Li-O 2 batteries. However, the scale-up of Li-O 2 technology to real application requires solving the mass transport limitation, especially for supplying oxygen to the cathode. Hence, the 'LABOHR' project proposes the introduction of a flooded cathode configuration and the circulation of the electrolyte, which is then used as an oxygen carrier from an external O 2 harvesting device to the cathode for freeing the system from diffusion limitation.

“…The works with a reasonable discharge capacity (ca. 130 mAh g -1 ) at a moderately increased temperature (40°C) [5,28,29]. Similarly, the temperature effect was found in the case of the Li/ LiFePO 4 cell working together with polymer electrolytes based on the quaternary ammonium cation, [NTf 2 -] anion and different co-polymers [30,31].…”

“…The LiFePO 4 cathode was studied in a series of ILs or polymer electrolytes based on ILs [5,13,[27][28][29][30][31][32][33]. Ionic liquids were based on pyrazolium, pyrrolidinium, imidazolium and tetraalkylammonium cations as well as -]/ LiFePO 4 cell worked with a capacity of 126 mAh g -1 at a C/10 rate without any molecular additive to the electrolyte [13].…”

Ternary [Li ? ][MePrPip ? ][NTf 2 -] and [Li ? ] [MePrPyrr ? ][NTf 2 -] room temperature ionic liquids (ILs) were obtained by dissolution of solid lithium bis(trifluoromethanesulfonyl)imide (LiNTf 2 ) in liquid N-methyl-Npropylpiperidinium bis(trifluoromethanesulfonyl)imide and N-methyl-N-propylpyrrolidinium bis(trifluoromethanesulfonyl)imide, respectively, and studied as electrolytes for the use in Li/LiFePO 4 or C(Li)/LiFePO 4 batteries. The cell worked properly in the presence of 10 wt% of vinylene carbonate (VC). Impedance-spectroscopy studies showed that the additive (VC) forms a protective coating on the anode. The LiFePO 4 cathode shows good efficiency (135 mAh g -1 ) working together with [Li ? ][MePrPip ? ][NTf 2 -] ? VC and [Li ? ][MePrPyrr ? ][NTf 2 -] ? VC ionic liquid electrolytes.The flash point of ionic liquid electrolytes containing 10 wt% of VC is above 300°C, which makes them practically nonflammable.
