In our paper a minor error was present in Table S6 in the Supporting Information. There, the input amounts of crude cobalt hydroxide and ammonium bicarbonate to the unit process dataset for battery-grade cobalt sulfate production in China were mixed up. These inputs should be 1.1 kg of crude cobalt hydroxide and 0.22 kg of ammonium bicarbonate, not the other way around. Table S6 in this correction is corrected accordingly, with the two corrected values highlighted in bold and italic. This error was not present in the life-cycle inventory modelling underpinning the results presented in the paper, and thus did not influence any other values or results in the paper.
