Definitions
- the present invention relates to a method and system for processing waste lithium ion batteries.
- Lithium-ion batteries are widely used in electric vehicles, mobile phones, laptop computers, etc.
- a lithium ion battery is composed of a positive electrode active material, a negative electrode active material, an electrolytic solution, a separator, a current collector, and the like.
- Lithium ion batteries include types such as NCM containing nickel, cobalt, manganese and lithium as positive electrode active materials and LFP containing iron, phosphorus and lithium as positive electrode active materials.
- lithium-ion batteries Since the lithium contained in such lithium-ion batteries is a rare metal, it is desirable to recover lithium from lithium-ion batteries that have been discarded after use (waste lithium batteries).
- Patent Document 2 discloses adding hydroxides of alkaline earth metals in order to turn fluorine and phosphorus into solid compounds during oxidative roasting.
- alkaline earth metals are less reactive than alkali metals, the alkali metal lithium combines with phosphate ions to form lithium phosphate (Li 3 PO 4 ), which is insoluble in water.
- Li 3 PO 4 lithium phosphate
- the waste lithium battery uses a positive electrode active material containing phosphorus, there is a concern that the decomposition of the positive electrode active material by roasting may not proceed with the addition of an alkaline earth metal. Elution becomes difficult.
- an object of the present invention is to provide a method and system for treating waste lithium ion batteries capable of improving the purity thereof.
- a method for treating waste lithium-ion batteries is a method for treating waste lithium-ion batteries for recovering lithium from waste lithium-ion batteries containing phosphorus as a positive electrode active material.
- a recovery step of recovering the lithium wherein the thermal decomposition step comprises a roasting step of roasting the waste lithium ion battery at a predetermined first temperature; and a mixing step of mixing an alkali metal salt other than lithium with the positive electrode active material.
- a waste lithium ion battery processing system is a waste lithium ion battery processing system for recovering lithium from a waste lithium ion battery containing phosphorus as a positive electrode active material, A thermal decomposition system that thermally decomposes a lithium ion battery by roasting to produce a roasted product containing the positive electrode active material, and a thermal decomposition system that immerses the produced roasted product in water to elute the lithium and then recover the lithium.
- the pyrolysis system includes a roasting device for roasting the waste lithium ion battery at a predetermined first temperature; and the positive electrode of the waste lithium ion battery before roasting in the roasting device.
- a mixing device for mixing an alkali metal salt other than lithium with the active material.
- the positive electrode active material of the waste lithium-ion battery and the alkali metal salt other than lithium are mixed before roasting the waste lithium-ion battery.
- the thermally stable positive electrode active material containing phosphorus is decomposed, and during elution, the phosphate ions and lithium contained in the positive electrode active material combine to make it insoluble in water. Since the phosphate ions and the alkali metal ions can be combined before lithium phosphate (Li 3 PO 4 ) showing Therefore, lithium can be eluted into water and recovered from a waste lithium-ion battery containing phosphorus as a positive electrode active material without a complicated process.
- the present invention has the effect of being able to dissolve and recover lithium in water from waste lithium-ion batteries containing phosphorus as a positive electrode active material without going through complicated steps, and to improve its purity.
- FIG. 1 is a schematic process diagram showing treatment steps in a waste lithium-ion battery treatment system according to an embodiment of the present invention.
- FIG. 2 is a schematic configuration diagram of a pyrolysis system that performs the pyrolysis step shown in FIG.
- FIG. 3 is a schematic configuration diagram of a recovery system that performs the recovery process shown in FIG.
- FIG. 1 is a schematic process diagram showing treatment steps in a waste lithium-ion battery treatment system according to an embodiment of the present invention.
- a waste lithium ion battery (waste LIB) to be processed by the processing system in the present embodiment is an LFP type lithium ion battery containing phosphorus in the positive electrode active material. More specifically, the LFP contains iron phosphate (LiFePO 4 ) as a positive electrode active material, graphite as a negative electrode active material, aluminum foil as a positive electrode current collector, and copper foil as a negative electrode current collector. This is the battery used.
- iron phosphate LiFePO 4
- This processing system targets large waste LIBs, that is, battery modules in which a plurality of battery cells of waste lithium-ion batteries are combined, and battery units in which a plurality of battery modules are combined.
- a battery unit is configured by housing, for example, a plurality of electrically connected battery modules, a control device, and a cooling device in a housing.
- This processing system is assumed to remove waste LIBs mounted on electric vehicles and hybrid vehicles, for example, and process the waste LIBs in the state of being removed, that is, the battery units or battery modules without dismantling. ing.
- the processing system in the present embodiment includes a thermal decomposition step P1 of thermally decomposing waste LIB and roasting the powder containing the obtained active material, and adding water to the roasted active material.
- the treatment process includes a recovery step P2 of recovering lithium after the lithium is eluted by immersion.
- the thermal decomposition process P1 includes a pretreatment process P11, a crushing and sorting process P12, a mixing process P13, and a roasting process P14.
