Phase Fraction Modulation Enhances Li <sup>+</sup> /Na <sup>+</sup> Diffusion Disparity in Spent LiFePO <sub>4</sub> Cathodes for Efficient Lithium Extraction from Brine
recovery rate can reach 99% within 40 min. Furthermore, the economic and environmental analysis indicated that the new strategy yields 528% higher profit ($7.23 per kg of SLFP), 40.5% reduction in energy demand and 67.8% reduction in greenhouse gas (GHG) emissions compared to conventional pyrometallurgy. It bypasses the need for pre-sorting SLFP, enhancing SLFP recycling efficiency and promoting high-value use of lithium-containing brine through "urban mining".
