Ionic liquids, from fundamental structure and interactions to new energy storage technologies

Aleksandar Matic (Chalmers University of Technology, Sweden)

Ionic liquids (ILs) currently attract a large interest for a range of applications including energy technology, pharmaceuticals, and synthesis of new materials. However, they are also of high interest from a more fundamental point of view. Being just made up of ions coulombic interactions naturally dominate, but due to the generally bulky nature of the constituent ions there is in most cases also a large contribution from van der Waals forces. The presence of competing interactions leads to the formation of structural heterogeneities on the nm-length scale in ionic liquids in contrast to the situation in simple liquids. In this presentation I will review some of our recent work on the structure and interaction of Li-salt doped ionic liquids as well as highlight how they can contribute to the realisation of new energy storage technologies.
