Development of simple hydrometallurgy strategies for recovering cathode materials in spent LiFePO4 (LFP) batteries is highly desired, but the removal impurity metal components remains a complex and challenging task. Herein, we proposed passivation-driven mechanism high-selective leaching an Al(OH)3 template self-dissolution hydrothermal method regenerating hollow-structure LFP materials. Experimentally, 99.0% Li 98.7% Fe can be leached out while only 4.0% Al from electrode sheets under ambient temperature within 1.5 h, passivation layer, made up original Al2O3, ester AlF3, formed on foil after contact with citric acid, which inhibits corrosion Al. Through treatment, leachate regenerate to particles based that element transformed precipitation into soluble AlO2− as pH value increases reactants being consumed. After short annealing, regenerated delivers excellent capacity 153.3 mAh g−1 at 0.1 C retention rate 91.6% 2 100 cycles. This work simplifies process removing impurities achieves simultaneous recycling foil.

The rapid increase in use of lithium-ion batteries energy storage together with limited supply critical metals used and environmental concerns have led to the urgent need for sustainable recycling technologies these batteries. Li-ion battery chemistry, components, various designs, two main approaches recycling: pyrolysis hydrometallurgical techniques are discussed this review focusing on novel, green approach hydroxy acid leaching followed by a direct regeneration technique. This two-step emerging technique is compared other conventional methods emphasizing simplicity commercial potential. Current literature reporting developments scalable process pretreatment phases sorting, discharging, disassembly batteries, separation electrode coatings from current collectors, black mass carboxylic acids, graphite, adjustments Li, Ni, Mn, Co compositions, via co-precipitation or sol–gel formation detailed review. conclusion section focused gives an insight into challenges technology practical solutions that may help development mainstream technology.
