The National Science Foundation awarded a $275,000 Project Grant to Reqyrd Inc. under the NSF Technology, Innovation, and Partnerships program (CFDA 47.084) to develop separations of critical materials from lithium-ion battery black mass. The one-year project aims to establish domestic recyclability for energy materials like cobalt, lithium, manganese, carbon, and nickel that are currently reliant on imports. Through the exploitation of solubilities using sulfites, the grantee will determine empirical solubility data, demonstrate the selective and effective separation of battery constituents, and optimize operational parameters to reduce reagent use, decrease equipment needs, and produce battery-grade feedstocks for a demonstrated supply chain circularity. A key goal is separating manganese without expensive solvent techniques. The grantee will explore solubilities of nickel/cobalt/manganese/lithium sulfites as functions of temperature and pH, characterize precipitate forms, and investigate oxidation of sulfite precipitates to high purity sulfates.
