Semisolid redox flow batteries simultaneously address the need for high energy d. and design flexibility. The elec. percolating network and electrochem. stability of the flowable electrodes are key features that are required to fully exploit the chem. of the semisolid slurries. Superconcd. electrolytes are getting much attention for their wide electrochem. stability window that can be exploited to design high-voltage batteries. Here, we report on the effect of the ion concentration of superconcd. electrolytes on the electronic percolating network of carbonaceous slurries. Slurries based on different concentrations of lithium bis(trifluoromethane)sulfonamide in tetraethylene glycol di-Me ether (0.5, 3, and 5 mol/kg) at different content of Pureblack carbon (from 2 up to 12 wt %) have been investigated. The study was carried out by coupling electrochem. impedance spectroscopy (EIS), optical fluorescence microscopy, and rheol. measurements. A model that describes the complexity and heterogeneity of the semisolid fluids by multiple conductive branches is also proposed. For the first time, to the best of our knowledge, we demonstrate that besides their recognized high electrochem. stability, superconcd. electrolytes enable more stable and electronically conductive slurry. Indeed, the high ionic strength of the superconcd. solution shields interparticle interactions and enables better carbon dispersion and connections.
