Electrochemical properties of organic electrolyte solutions containing 1-ethyl-3-methylimidazolium tetrafluoroborate salt

Electrochemical properties of organic electrolyte solutions containing... Organic electrolytes were prepared by using a mixture of propylene carbonate (PC) and dimethyl carbonate (DMC) as solvent, tetraethylammonium tetrafluoroborate (TEABF4) as salt, and different amounts of 1-ethyl-3-methylimidazolium tetrafluoroborate (EMImBF4) as additive. The bulk resistance and ionic conductivity of the organic electrolytes were investigated using the alternating-current (AC) impedance method and an ionic conductivity meter, respectively. The capacitance of the organic electrolytes was analyzed by cyclic voltammetry. From the experimental results, with increasing EMImBF4 content, the ionic conductivity and capacitance of the electrolyte increased whereas the electrolyte resistance and electrode resistance decreased. In particular, for EMImBF4 content of 15 vol% with 0.1 M TEABF4 in PC/DMC solvent, the electrolyte showed the best capacitance. However, when the EMImBF4 content exceeded 15 vol%, the capacitance did not increase further and the interfacial resistance and bulk resistance no longer changed. From the interfacial resistance results, it is concluded that the capacitance did not change because the charge-transfer mobility was similar at the interface between electrode and electrolyte. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals
