Abstract
The present application provides a system and method for discharging and processing of lithium ion batteries to extract one or more metals. The extracted metals are in a powder form that can be reused at second stage processing facilities. The extracted metal powder can include lithium and at least one of cobalt, nickel, manganese, and carbon.
Claims11
A battery processing system comprising:
- a sorter configured to sort a mixed chemistry of batteries comprising lithium ion (Li-ion) batteries and one or more of alkaline, nickel metal hydride (Ni-MH) and nickel cadmium (Ni—Cd) batteries, such that the Li-ion batteries are separated from the one or more of alkaline, Ni-MH and Ni—Cd batteries into bins;
- a packaging removal device configured to remove packaging from the Li-ion batteries to expose Li-ion cells of the Li-ion batteries;
- a puncturing device configured to puncture the Li-ion cells before discharging, wherein the puncturing allows electrolyte in the punctured Li-ion cells to dry out to increase a speed of electrolyte evaporation and decrease a Li-ion processing time of the battery processing;
- a conveyor configured to deposit the punctured Li-ion cells in water for fire or fume mitigation;
- a kiln or salt bath configured to discharge the punctured Li-ion cells;
- a cooling retort configured to cool the discharged and punctured Li-ion cells;
- a shredder configured to shred the cooled, discharged, and punctured Li-ion cells into pieces;
- a magnetic separator configured to remove iron (Fe) from the shredded pieces;
- and
- a pulverizer configured to pulverize remaining shredded pieces of the pieces into a mixed powder including Li and at least one powder selected from the group consisting of cobalt (Co), nickel (Ni), manganese (Mn) and carbon (C).
7 more elements
An integrated recycling system for processing electric vehicle (EV) modules, the system comprising:
- a puncturing device configured to puncture the EV modules before discharging, wherein the puncturing allows electrolyte in the punctured EV modules to dry out to increase affects a speed of electrolyte evaporation and decrease a Li-ion processing time;
- a conveyor configured to deposit the punctured EV modules in water for fire or fume mitigation;
- a kiln configured to discharge the punctured EV module by heating;
- a cooling retort configured to cool the discharged and punctured EV modules;
- a shredder shredding the discharged EV modules into pieces;
- a magnetic separator for separating metal-containing interior cells from plastic remains;
- and a pulverizer for pulverizing the metal-containing interior cells into a mixed metal powder.
