Provided are a battery-level Ni—Co—Mn mixed solution and a preparation method for a battery-level Mn solution, the steps thereof comprising: acid dissolution (S1), alkalization to remove impurities (S2), synchronous precipitation of calcium, magnesium, and lithium (S3), deep ageing to remove impurities (S4), synergistic extraction (S5), and refining extraction (S6). The steps of deep ageing to remove impurities (S4) and synergistic extraction (S5) comprise: performing deep ageing on a filtrate obtained from the step of synchronous precipitation of calcium, magnesium, and lithium (S3), and after performing filtration to remove impurities, obtaining an aged filtrate; using P204 to extract the aged filtrate and obtain a loaded organic phase, and subjecting the loaded organic phase to staged back-extraction to obtain the battery-level Ni—Co—Mn mixed solution and a Mn-containing solution. By means of the cooperation between the multiple process steps of synchronous precipitation of calcium, magnesium, and lithium (S3), deep ageing to remove impurities (S4), and synergistic extraction (S5), the impurity content of the obtained battery-level Ni—Co—Mn mixed solution is significantly lowered, and the battery-level Ni—Co—Mn mixed solution can be directly used to prepare a lithium battery ternary precursor material. At the same time, the battery-level Mn solution can also be obtained, which is favorable for large-scale applications of the process and increasing economic benefits.

A method for recycling a battery including the following steps: a) dissolution of a battery waste, for example an electrode, including lithium and a metal selected from cobalt and manganese, such that a solution to be treated containing lithium ions and metal ions is formed, b) addition of a peroxymonosulfate salt to the solution to be treated, the solution to be treated being regulated at a pH ranging from 1 to 4 when the metal is cobalt or at a pH ranging from 0.1 to 2.5 when the metal is manganese, such that the metal ions are selectively precipitated in the form of metal oxyhydroxide, c) separation of the lithium ions from the solution to be treated. Advantageously, the solution further comprises nickel ions.

A spent and/or decommissioned accumulator treatment plant and process, wherein a plurality of objects originating from separate waste collection of spent and/or decommissioned accumulators, nominally comprising lead-acid accumulators and accumulators and objects of a different type, are subject to an X-ray scan. If an analysis of the X-ray scan indicates that an object is not a lead-acid accumulator, and in particular is a lithium-ion battery or accumulator, it is deviated out of the treatment workflow, that comprises grinding the objects and separating lead from other materials.

An apparatus, method and system are provided to recover constituent components from single use batteries. In particular, the apparatus, method and system may be used to recover zinc and manganese in the form of sulfates from depleted commercial which in turn may be subsequently used for other applications, such as micronutrients and fertilizers.

A method for recycling All solid state batteries (ASSBs), the method including: receiving a recycling stream of ASSBs comprising an electrolyte comingled with at least one charge material; introducing a passivating substance for neutralizing an undesired reaction or discharge of the charge materials from the batteries defining the recycling stream; agitating the batteries in the recycling stream in the presence of the passivating substance for liberating the charge materials and electrolyte stored therein; and recovering the charge material and the electrolyte from the agitated batteries, and such that the passivating substance combines with the agitated batteries for generating a beneficial product thereby recycling ASSBs.

A process for the recovery of lithium from waste lithium ion batteries or parts thereof is disclosed. The process comprising the steps of A) providing a crude lithium hydroxide as a solid, which contains fluoride; and (B) dissolving the crude lithium hydroxide solid with a lower alcohol such as methanol or ethanol provides good separation of lithium in high purity.

An apparatus for processing a waste battery is proposed. The apparatus includes a conveying unit having a conveying belt rotated by a plurality of rotating shafts which are rotated to convey the supplied waste battery in one direction, a pulverizer disposed on a position along a travelling direction of the conveying unit to pulverize the waste battery, a heater disposed on a downstream side of the pulverizer to heat dust formed by the pulverizer, a collector collecting the dust which passes through the pulverizer and the heater, a filter part filtering a pulverized material of the collector, a mixer supplying an additive to the dust discharged from a discharge pipe of the filter part, and a compressor compressing a mixture mixed in the mixer.

Provided is a method for separating lithium from a lithium solution containing lithium by 200 mg/L or more and fluorine by 20 mg/L or more, the method including: a first removal step of adding a first component, which solidifies the fluorine contained in the lithium solution, to the lithium solution and removing the fluorine solidified to obtain a F-removed liquid; and a second removal step of adding a second component, which solidifies the first component remaining in the F-removed liquid, to the F-removed liquid and removing the first component solidified to obtain a first component-removed liquid.

A fluidized bed reactor according to an embodiment of the present disclosure includes a reactor body, and a dispersion plate coupled to a bottom portion of the reactor body. The dispersion plate may include a base plate and injection columns protruding from a top surface of the base plate. The injection columns include first injection columns arranged at a central portion of the dispersion plate, and second injection columns arranged at a peripheral portion of the dispersion plate. The second injection column has a greater height than a height of the first injection column. A reactive gas is uniformly injected to a wall surface of the reactor through the dispersion plate, thereby increasing a recovery ratio for an active metal of a lithium secondary battery.
