Several types of carbon pastes were prepared, examined and characterized. Particular attention has been paid to the changes of the ohmic resistance, relative to the dependence on the composition of carbon ionic liquid electrodes (CILEs) and the proportions of the respective constituents used. The results were compared with those of "classic" carbon paste electrode (CPE) based on graphite powder and the differences in physical as well as electrochemical properties were discussed and explained. As found, the most evident difference was in the optimal carbon-to-binder ratio of the paste. Finally, some problems connected with homogeneity and stability of carbon paste mixtures are also discussed.
