This is in accordance with Li's report. The polarization voltage between the reduction peak and the oxidation peak is about 0.4 V, and the polarization increases gradually with the cycle …
WebThese observations imply that in the LiTFSI-based concentrated or localized concentrated electrolytes, TFSI − anions participate in the electrochemical oxidation rather than reduction. 55 That is, FSI − shows higher activity than TFSI − in SEI formation. Web1 jul. 2024 · From Table I it is evident that the addition of 1 m LiTFSI to the electrolyte reduces the gas solubility for most of the solvent–gas combinations. Only the solubility of O 2 and of N 2 in DMSO is increased in the electrolyte with 1 m LiTFSI. The decrease in solubility when a salt is added can be explained by the salting out effect.
