Azolylborates for Electrochemical Double Layer Capacitor Electrolytes

Robert Francke, D. Cericola, R. Kötz and Siegfried R. Waldvogel


Asymmetric tetraalkylammonium salts of azolylborates were synthesized and studied with respect to their suitability as supporting electrolytes in electrochemical double layer capacitors. In contrast to current conducting salts used in this device, azolylborates exhibit an excellent stability towards thermal load and moisture. In addition to good conductivity and stability towards cathodic reduction we found certain limitations when more positive potentials were applied.
