Abstract:
    The related recovery and process method for waste secondary Li-ion cell comprises: separating cell shell, circuit board and cell core by mechanical means; discharging the core; then separating to obtain the shell and coiling material of cell core; putting the last one into some organic solvent to separate the cell polar material from collector foil, filtering to obtain the foil and active material for recovery by chemical way. With small investment, this invention is simple and safe and high yield.
