Utilization of waste sodium sulfate from battery chemical production in neutral electrolytic pickling [PDF]
Journal of Cleaner Production, 2021 Abstract Several industrial activities produce metal sulfates, which are controlled by strict limitations for wastewater concentrations of sulfate. One emerging area where these activities occur is the production of lithium-ion battery chemicals in which sodium sulfates are formed because of cathode precursor co-precipitation.
