Structural and Spectroscopic Studies on Electrolytes Containing Novel Salts Dedicated to Lithium-Ion Batteries
Due to this, the importance of the research on novel salts for batteries' electrolytes grew more and more important. The focus was put on looking for novel lithium salts which dissociate well in aprotic solvents and are electrochemically and thermally stable.
In the present study, spectroscopic and structural properties of the solvates of the lithium salts with fluorine-free heteroaromatic anion are researched. The main impact is put on complexes of the salts with dimethyl ethers of ethylene glycol oligomers (glymes) and organic carbonates.
Correlation between crystal structures, obtained from X-ray diffraction experiments on the single crystals with vibrational spectroscopy data (FTir and Raman) should make the prediction of the cation-anion-solvent molecule interactions in the liquid systems possible.
The discovering and understanding of phenomena related to the organization of such systems in the solid state is crucial for the elaboration of novel electrolytes. Gained knowledge will be helpful in the design of novel compounds with defined properties and in optimization of the working systems.
