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.

Although the rapid development of new energy vehicles (NEV) has contributed greatly to China's carbon emission reduction, it also brought about a problem that needs be solved, namely effective recycling waste batteries. Existing batteries is plagued by series problems such as single channel, inconsistent standards, lack technology, rampant irregular enterprises, and low consumer participation. Meanwhile, due immaturity market, clarity existing regulations, supervision management, above are becoming more serious. Therefore, solve these problems, this paper constructs four-party stochastic evolutionary game model including government regulators, NEV third-party consumers. Focus on analyzing impact relevant parameters choice strategies participants, put forward proposed countermeasures promote based conclusions.
