In recent years, renewable energy has been attracting attention. However, since the amount of electricity generated is affected by weather conditions, thus, it is important to use a secondary battery to store the generated electricity. One of the promising energy storage technologies is a redox flow battery in which active materials’ powder are suspended. In this study, particles of hydrogen storage alloy were dispersed in KOH solution. The apparent viscosity, relative viscosity and battery performance of the prepared slurries were investigated. It was found that the particles dispersion state in the slurry changed when the slurry was heat treated, thus it is important to evaluate the slurry properties after heat treatment. When changing the type of added polymers, it was shown that the slurry containing a sodium polycalboxylate with a molecular weight of 250000 showed the better battery performance even though its apparent and relative viscosities were not the smallest among the all slurries used in this study.
