Resumen:
In situ infrared subtractive normalized Fourier transform infrared spectroscopy (SNIFTIRS) experiments were performed simultaneouslywith the electrochemical experiments relevant to Li-air battery operation on gold cathodes in ionic liquid PYR14TFSI basedelectrolyte. Ionic liquid anion was found to be stable, while the cation PYR14+ was found to decompose in studied conditions. Inoxygen saturated LiTFSI containing PYR14TFSI electrolyte carbon dioxide and water were formed at potential 4.3 V either with orwithout previous oxygen electro-reduction reaction. However in deoxygenated LiTFSI contacting ionic liquid no formation of CO2or water was observed, suggesting oxygen presence to be crucial in carbon dioxide production.
