Electrolytes in lithium-ion batteries: state of the art and future trend — •Andrea Balducci — Institute of Physical Chemistry, University of Muenster, Muenster, Germany

Lithium ion batteries dominate the consumer portable electronic and telecommunications market and they are also indicated as the most promising option for the next generation of hybrid and electric vehicles (HV, EV). However, when the present lithium ion technology is considered, the safety of batteries appears to be one of the main drawbacks holding the introduction of this technology in HV and EV. The commercial systems nowadays available use electrolytes commonly based on organic carbonates (e.g. Propylene Carbonate, PC, Ethylene Carbonate, EC) but since these electrolytes are flammable their use poses a serious safety risk and strongly reduces the battery operative temperature range. For such reasons, alternative electrolytes have been proposed and tested in the last decade. Between them, ionic liquids (ILs) instead of organic carbonates appear to be promising.
