Non-aqueous electrolytes for electrochemical capacitors

This review supplies an overview about the most recent work which has been carried out toward the realization of innovative non-aqueous electrolytes for high energy electrochemical capacitors (EDLCs). The solvents, conducting salts and ionic liquids proposed in the past years are discussed, and their impact on the EDLC performance is critically analyzed. Furthermore, the actual status of the research dedicated to the identification, characterization and application of novel electrolytes is analyzed. The aim of this latter section is to supply indications about the most important aspects, which still need to be investigated in order to realize a novel generation of electrolytes suitable for the realization of high energy EDLCs.
