Four anodes with similar Ni-Co-O loadings and chemical characteristics but distinct morphologies are fabricated by ultrasonic spraying catalyst inks of varying solvent composition (pure water versus a water-ethanol mixture) and drying temperatures (50 and 150 °C) on nickel (Ni) plates. Upon varying solvent compositionparticles in the water-based ink exhibited lower stability than particles in the water-ethanol-based inkboosting the particle connectivity in the layers.
