发明名称 Method for the recovery of constituents of spent lithium cells
摘要 <p>The process comprises totally discharging unprotected lithium cells (25), mechanically crushing (25) the discharged lithium cells under a low oxygen atmosphere in which a first portion of lithium compounds is reacted, introducing the crushed lithium cells into a protic liquid in which a second remaining portion of lithium compounds are reacted and hydrogen is formed to generate energy, and discharging the unreacted lithium compounds. The totally discharging step includes removing electronic components from the lithium cell. The process comprises totally discharging unprotected lithium cells (25), mechanically crushing (25) the discharged lithium cells under a low oxygen atmosphere in which a first portion of lithium compounds is reacted, introducing the crushed lithium cells into a protic liquid in which a second remaining portion of lithium compounds are reacted and hydrogen is formed to generate energy, and discharging the unreacted lithium compounds. The totally discharging step includes removing electronic components from the lithium cell. The crushing step is performed using a shredder. The oxygen is present in an amount of less than 10 vol.%. The low-oxygen atmosphere is produced by an oxygen pump. The oxygen pump is partly driven by recovered energy obtained from the totally discharging step. The protic liquid includes water, alcohols, amines, amides, carboxylic acids, and mineral acids. The discharged lithium cells are transported to the protic liquid in counter current manner. The process further comprises controlling a volume of flow of the protic liquid and controlling temperature of the protic liquid.</p>
