b'Recovering Cobalt fromNovel electrochemical purification process removes impurities Spent Lithium-ion Batteriesfrom spent lithium-ion batteries with no waste generation.Using ElectrochemicalE xpanding the electric vehicle market brings with it exponential growth in the use of lithium-ion batteries, which need lithium and transition metals Membrane Reactor withoutincluding cobalt, nickel, and manganese for their cathodes. The import Chemical Consumption reliance of lithium, cobalt, nickel, and manganese in United States is 2550%, 78%, 48%, and 100%, respectively. Recycling spent lithium-ion batteries is an effective strategy to mitigate the risk of supply chain disruption. Hydrometallurgy is the most promising methodology to recycle lithium-ion batteries because it is more efficient with better selectivity and less energy use. To recycle the spent batteries at an industrial scale, hydrometallurgy has the drawbacks of high chemical consumption, inducing high cost and negative environmental impact. In this project, a novel electrochemical PROJECT NUMBER:membrane reactor was designed and proven. The reactor removed the impurities 21A1057-024 from lithium-ion batteries, including copper, iron and aluminum, to approximately 1 TOTAL APPROVED AMOUNT:ppm by just using electricity, air, and water. The purified leachate maintains 99.5% of $135,000 over 1 year the nickel, 95.4% of the cobalt and 99.14% of manganese from the original leachate solution, and the leachate can be directly applied to cathode precursor synthesis. In PRINCIPAL INVESTIGATOR:comparison, the chemical precipitation method consumes a significant amount of Qiang Wang chemicals, such as sodium hydroxide, and maintains only 55.2% of nickel and 76.1% CO-INVESTIGATORS: of cobalt. Additionally, the electrochemical purification process does not introduce Luis Diaz Aldana, INLextra impurities, and the reactor restoration process generates valuable by-product John Klaehn, INL sulfuric acid. This electrochemical process can reduce the cost occurred by material consumption due to the much less chemical consumption and the valuable by-product generation. The process mitigates waste emissions because no impurities are introduced, and no greenhouse gas is produced. INTELLECTUAL PROPERTY:Wang, Q., L. A. Diaz Aldana, D. M.
