报告摘要：Lithium-ion batteries are becoming increasingly important for electrifying the modern transportation system and, thus, hold the promise to enable sustainable mobility in the future. However, their large-scale application is hindered by severe safety concerns when the cells are exposed to mechanical, thermal, or electrical abuse conditions. These safety issues are intrinsically related to their superior energy density, combined with the (present) utilization of highly volatile and flammable organic-solvent-based electrolytes. Improving the thermal stability of electrolytes and the safety of LIBs is one of the imperatives of our investigations.

The challenges, which so far prevent the widespread replacement of organic carbonate-based electrolytes, will also be mentioned. Starting from rather “facile” electrolyte modifications by (partially) replacing the organic solvent or lithium salt and/or the addition of functional electrolyte additives, conceptually new electrolyte systems, including ionic liquids (ILs) are considered. Ionic liquid/organic solvent mixtures are investigated as potential optimal electrolytes for lithium-ion batteries (LIBs) that can combine low flammability, good thermal stability and high electrical conductivity. That approach provides a great chance of developing highly functionalized, new electrolyte systems, which may overcome the afore-mentioned safety concerns related to conventional electrolytes, also offering enhanced mechanical, superior thermal performance, electrochemical performance and safety tolerance to both overcharge and thermal abuse.
