In Situ Infrared Spectroscopy Study of PYR14TFSI Ionic Liquid Stability for Li–O2Battery
Source abstract
Abstract
In situ infrared subtractive normalized Fourier transform infrared spectroscopy (SNIFTIRS) experiments were performed simultaneously with the electrochemical experiments relevant to Li-air battery operation on gold cathodes in ionic liquid PYR 14 TFSI based electrolyte. Ionic liquid anion was found to be stable, while the cation PYR 14 + was found to decompose in studied conditions. In oxygen saturated LiTFSI containing PYR 14 TFSI electrolyte carbon dioxide and water were formed at potential 4.3 V either with or without previous oxygen electro-reduction reaction. However in deoxygenated LiTFSI contacting ionic liquid no formation of CO 2 or water was observed, suggesting oxygen presence to be crucial in carbon dioxide production.
