Abrégé

A modified lithium nickel cobalt manganese oxide positive electrode material and a preparation method therefor, belonging to the technical field of positive electrode materials. The preparation method comprises: mixing and reacting a mixed modification liquid with a lithium nickel cobalt manganese oxide matrix to be coated, and carrying out freeze drying, the mixed modification liquid being obtained by mixing a modified chitosan coating liquid and conductive particles modified by a silane coupling agent, the modified chitosan coating liquid being obtained by mixing a solvent and modified chitosan obtained by modifying chitosan with a carboxyl-containing imidazole compound, and the silane coupling agent being ethoxy-containing silane.

Abrégé

The present invention relates to the technical field of used lithium battery recycling. Disclosed is a treatment method for used lithium battery leachate. The treatment method for used lithium battery leachate comprises copper removal, ferro-aluminum removal, nickel-cobalt-manganese precipitation, primary lithium precipitation, secondary lithium precipitation and phosphorus removal which are performed successively. During the phosphorus removal, using an excess of calcium salt in the reaction makes an obtained calcium phosphate residue alkaline, and calcium phosphate replaces an alkali for traditionally adjusting pH values such that the calcium phosphate residue is effectively utilized. Thus, calcium phosphate is used as a resource in order to recycle valuable metal lithium therein. Intermediate products, i.e. a ferro-aluminum residue and a nickel-cobalt-manganese hydroxide residue, each have a relatively low impurity content, thus reducing the production cost of the whole process, and increasing the economic benefit.

Abrégé

The present invention belongs to the technical field of lithium-ion batteries, and disclosed is a method for recovering a waste lithium battery positive electrode material. The method comprises: subjecting a waste positive electrode sheet to irradiation treatment in an oxidizing atmosphere, then soaking same in an organic solvent, then screening same to obtain a slurry and an aluminum foil, and then removing moisture from the slurry to obtain a positive electrode material. It can be seen that in the method for recovering a waste lithium battery positive electrode material provided in the present invention, polyvinylidene fluoride is dehydrogenated and defluorinated in an oxidizing atmosphere by means of irradiation treatment to produce a conjugated double bond, and the conjugated double bond is then directly oxidized and broken, thereby reducing the molecular weight of the polymer. Moreover, in the oxidizing gas atmosphere, a compact oxidation film can be generated on the surface of the aluminum foil, which is beneficial for ensuring more complete recovery of the aluminum foil. An organic solvent is then used for soaking, such that the positive electrode material falls off the surface thereof, and finally, the slurry obtained by screening is recovered to obtain the positive electrode material.

Abrégé

Disclosed in the present invention are a reparative regeneration method for a positive electrode material of an alkali metal ion battery, a positive electrode material, and the use. The reparative regeneration method comprises: pretreatment: doping a recycled positive electrode material by means of using halide ions, and/or subjecting Ni3+in the positive electrode material to reduction by using alkyl radicals; alkali metal supplementation: supplementing alkali metal ions to the pretreated positive electrode material; and sintering: sintering the positive electrode material supplemented with the alkali metal ions. The present application dopes the recycled positive electrode material by means of using halide ions; and halide ion doping can provide an effect in attracting the alkali metal ions, thus reducing the migration energy of the alkali metal, and stabilizing the material framework. The alkyl radicals have the reducibility to reduce Ni3+into Ni2+, thus reducing the diffusion resistance of alkali metal ions according to the principle of charge conservation. Therefore, the halide ions and the alkyl radicals both enable waste positive-electrode powder to have a better alkali metal supplementing effect during the alkali metal supplementing process.

Abrégé

Disclosed are a waste lithium battery positive electrode sheet recycling treatment device and a method thereof. According to a table of reactivity series of metals, iron is stronger than hydrogen, and thus iron ions in a ferric sulfate salt washing solution preferentially react with part of aluminum foil to generate aluminum ions and ferrous ions and hydrogen ions are inhibited from reacting with the aluminum foil to generate hydrogen. In addition, the ferrous ions and lithium nickel manganese cobalt oxides in positive electrode material powder undergo redox reaction, so that the hydrogen ions are consumed and the ferrous ions are oxidized into iron ions, and thus the iron ions achieve dynamic balance in a whole ultrasonic salt washing process and the hydrogen ions are always inhibited from reacting with the aluminum foil to generate hydrogen. Therefore, the use of ferric sulfate ultrasonic salt washing not only can reduce generation of hydrogen, but also can avoid the use of an organic solvent and generation of aluminum powder, thereby effectively improving the safety of the waste lithium battery positive electrode sheet recycling treatment device.

Abrégé

A method for measuring the total phosphorus content of a non-ferrous metal extraction waste liquid, wherein the key is to use a ferrate solution for digestion. The standard redox potential of a ferrate is much higher than those of other inorganic oxidizing agents, so that organophosphorus in a test sample can be fully digested to ensure the accuracy of the total phosphorus content; in addition, a product obtained after ferrate reduction is a ferric hydroxide suspension having a flocculation effect, so that trace heavy metal ions, such as arsenides, sulfides and chromium compounds, in the test sample can be effectively removed, the turbidity and chromaticity of the test sample can be effectively reduced, and the test sample having high turbidity can be directly digested without pretreatment, exerting a synergistic effect of oxidation, flocculation, adsorption and precipitation. Furthermore, trace cobalt and nickel ions in the non-ferrous metal extraction waste liquid can catalyze the accelerated decomposition of the ferrate, so that adding excess ferrate solution does not affect the subsequent measurement.

Abrégé

The present application relates to the technical field of lithium iron phosphate battery recycling, and discloses a method for recycling a lithium iron phosphate battery. The present application employs a selective stepwise leaching process for lithium and copper-aluminum, thus preventing copper-aluminum impurities from entering into a leaching solution of lithium. The leaching solution of lithium may be directly precipitated to prepare product lithium carbonate, thus preventing lithium loss caused by the precipitation of the copper-aluminum impurities, and preventing the lithium recycling rate from being impacted thereby. According to the present application, iron phosphate and graphite from the second leaching residue are used as a negative electrode, lithium in lithium-precipitation tailings and wash water is enriched by using an electrodeposition method, and enriched lithium iron phosphate is again returned to a selective lithium leaching process. The process resolves the following problems present in a traditional process of lithium enrichment by evaporation crystallization followed by lithium precipitation with sodium carbonate: a. an acid needs to be added before evaporation crystallization, and the acid is consumed for carbonate removal; b. energy consumption is high in the evaporation crystallization; and c. sodium sulfate crystals precipitated during the evaporation process carry away some lithium salts, causing lithium loss and resulting in a lower overall lithium recycling rate.
