Properties of Sulfolane Based Aprotic Electrolytes

Robust High-performance Dye-sensitized Solar Cells Based on Ionic Liquid-sulfolane Composite Electrolytes

Novel ionic liquid-sulfolane composite electrolytes based on the 1,2,3-triazolium family of ionic liquids were developed for dye-sensitized solar cells. The best performing device exhibited a short-circuit current density of 13.4 mA cm(-2), an open-circuit voltage of 713 mV and a fill factor of 0.65, corresponding to an overall power conversion efficiency (PCE) of 6.3%. In addition, these devic...

EDLC performance of carbide-derived carbons in aprotic and acidic electrolytes

This study shows that carbide-derived carbons (CDCs) with average pore size distributions around 0.9 to 1 nm and effective surface areas of 1300-1400 m g provide electrochemical double layer capacitors with high performances in both aqueous (2M H2SO4) and aprotic (1M (C2H5)4NBF4) in acetonitrile) electrolytes. In the acidic electrolytic solution, the gravimetric capacitance at low current densi...

Chemistry and applications of polysaccharide solutions in strong electrolytes/dipolar aprotic solvents: an overview.

Biopolymers and their derivatives are being actively investigated as substitutes for petroleum-based polymers. This has generated an intense interest in investigating new solvents, in particular for cellulose, chitin/chitosan, and starch. This overview focuses on recent advances in the dissolution and derivatization of these polysaccharides in solutions of strong electrolytes in dipolar aprotic...
