Carbon-black gels are viscoplastic, highly conductive complex fluids of particular interest for use in semisolid flow batteries. The authors present an apparatus for performing simultaneous rheological and electrical measurements on such materials, and realize a number of physical insights into the rheology and microstructural evolution of carbon-black gels at rest, in transient flow, and in steady shear. This capability and the results it can yield should interest a wide range of researchers in engineering and soft-matter physics.
