The　extraction　of　Li　from　the　spent　LiFePO4　cathode　is　enhanced　by　the　selective　removal　using　interactions　between　HCl　and　NaClO　to　dissolve　the　Li+　ion　while　Fe　and　P　are　retained　in　the　structure.　Several　parameters,　including　the　effects　of　dosage　and　drop　acceleration　of　HCl　and　NaClO,　reaction　time,　reaction　temperature,　and　solid-liquid　ratio　on　lithium　leaching,　were　tested.　The　Total　yields　of　lithium　can　achieve　97%　after　extraction　process　that　lithium　is　extracted　from　the　precipitated　mother　liquor,　using　an　appropriate　extraction　agent　that　is　a　mixture　of　P507　and　TBP　and　NF.　The　method　also　significantly　reduced　the　use　of　acid　and　alkali,　and　the　economic　benefit　of　recycling　is　improved.　Changes　in　composition,　morphology,　and　structure　of　the　material　in　the　dissolution　process　are　characterized　by　inductively　coupled　plasma　optical　emission　spectrometry,　scanning　electron　microscope,　X-ray　diffraction,　particle　size　distribution　instrument,　and　moisture　analysis.
