AbstractIn the current study, we attempt to formulate and characterize aqueous electrode suspensions (anolytes) composed of carbon black (KB) and sodium titanate (Na2Ti3O7; NTO) dispersed in branched micelle solution. The suspensions were characterized by cyclic voltammetry, impedance spectroscopy, rheology, and simultaneous rheo-impedance spectroscopy. The branched micelle solution showed peculiar microstructure with wide working potential of 2.59 V enabled it to be an excellent dispersing medium for conductive KB. Due to excellent wettability, KB dispersions were electrically percolated at low KB content (0.9 wt%) forming a three-dimensional conductive network with significant flexibility enabled them to retain the electrical conductivity under flow. At 1.5 wt% KB, the anolytes could tolerate high load (25 wt%) of NTO without severe rise in the rigidity and conductivity under static and flow modes. Whilst those formulated in the saturated KB dispersions manifested a serious decrease in the conductivity at high load of NTO nanorods.
