Abstract
Lithium-ion batteries (LIBs) currently dominate the commercial rechargeable battery market due to their high ionic conductivity and moderate compatibility. To enhance the development and safety of future LIBs, ionic liquids (ILs) have been introduced as additives. For the first time, we present the Lewis acid/base responses of nine ILs in terms of donor number (DN), calculated using 7Li NMR spectroscopy. The anionic component of the ILs significantly influences the DN through its interaction with lithium ions. In addition, the DN of three carbonate solvents was determined using both 7Li and 23Na NMR spectroscopy, showing that DN of solvent is affected by the probe ion and solvent structure. These findings offer valuable insights for selecting appropriate solvents for future electrolyte development in LIBs.
期刊介绍：
The Korean Journal of Chemical Engineering provides a global forum for the dissemination of research in chemical engineering. The Journal publishes significant research results obtained in the Asia-Pacific region, and simultaneously introduces recent technical progress made in other areas of the world to this region. Submitted research papers must be of potential industrial significance and specifically concerned with chemical engineering. The editors will give preference to papers having a clearly stated practical scope and applicability in the areas of chemical engineering, and to those where new theoretical concepts are supported by new experimental details. The Journal also regularly publishes featured reviews on emerging and industrially important subjects of chemical engineering as well as selected papers presented at international conferences on the subjects.
