| Abstract Scope |
The conventional lithium extraction from used electric vehicle lithium-ion batteries (LIBs) employs hydrometallurgical processes, involving dissolution with strong inorganic acids and oxidants at high temperatures. These acids are corrosive, generate significant wastewater, and pose risks of emitting toxic gases during reactions with compounds present in end-of-life LIBs. This study explores a novel solvo-metallurgical process using deep eutectic solvent (DES) made from choline chloride and urea, which is green, non-toxic, and liquid at room temperature. The DES, prepared by mixing choline chloride and urea at a 1:2 molar ratio at 80°C, extracted lithium from crushed battery black mass (BM) at 90°C. Results showed 100% lithium extraction with DES, compared to 79% with sulfuric acid and hydrogen peroxide. The extracted lithium can be electro-deposited onto anodized titanium to produce high-quality lithium metal. |
