成果简介	NOVELTY - Advanced hybrid re-mineralized recovery process to extract critical metals from end-of-life lithium-ion batteries by: (i) collecting, end-of-life lithium-ion batteries in storage bin and segregated based on their size i.e. large and small batteries; (ii) disassembling, large batteries into small cell packs and subjecting to pre-treatment module along with small size batteries; (iii) immersing, collected material into liquid immersion, and stabilizing the batteries; (iv) feeding, the batteries to primary shredding module; (v) processing, the finely shredded material via impact milling module; (vi) separating and refining the material; (vii) dissolution of black mass by using dissolution agents to form solution of precipitated solid residues and soluble metal salts; (viii) filtering; (ix) dissolving, critical metal CM-1 and CM-2 in the liquid phase inside chemical reactor and separating these selective metals by adding H+ ions; and (x) dissolving solid residue in specific chemicals. USE - The process is useful as advanced hybrid re-mineralized recovery process for extracting critical metals from end-of-life lithium-ion batteries e.g. lithium, cobalt, nickel and manganese. ADVANTAGE - The recycling process: recovers critical metals like lithium, cobalt, nickel, and copper, reduces reliance on mining and lowers production costs; mitigates mining-related environmental degradation, including habitat destruction, water pollution, and carbon emissions; reduces hazardous waste in landfills, preventing toxic metal leaching, and lowers the carbon footprint compared to traditional extraction methods; provides proper recycling, prevents toxic substance release, protects public health; promotes a circular economy, conserving resources and supporting sustainable consumption and production; ensures a steady supply of critical materials for renewable energy, aiding climate targets; is efficient in recovering critical metals out of spent lithium-ion batteries at the highest purity levels; is an environmentally friendly process with no harmful emissions and discharge throughout the process; and is efficient and cost-effective promoting a sustainable circular economy in the battery value chain.
