Recycling of battery materials is a topic with room for improvements in the recycling of the materials present in current Li-ion and NiMH batteries. In this research, a recovery route for Ni as Tutton’s salts (M+2 M3+(SO4)2·xH2O) was investigated, of which Mohr’s salt ((NH4)2Fe(SO4)2*6H2O), a commonly utilized titration reagent, is an example. Similarly, both Ni and Co can form barely soluble compounds with NH4 + ions in an acidic sulfate media. The behavior of battery metal Ni was investigated as a function of NH4 + ion concentration, pH and temperature in single parameter variation experiments. Ni, along with Co, was obtained with ease at a low pH over other metals that could be considered impurities (e.g. Fe). However, the usage of NH4 + ions carries its own problems, e.g. in the subsequent downstream processes.
