A process is described for the recovery of the chemical components of the “black paste” resulting from the opening of dead alkaline and zinc-carbon batteries.

Provided herein is a method for recycling lithium-ion batteries in a polar solvent such as an aqueous media or water. The method disclosed herein isolates a mixture of anode and cathode materials from waste lithium-ion batteries. The separated electrode materials can easily be collected with high recovery rate, providing a rapid, efficient and low-cost method for recycling electrode materials from waste lithium-ion batteries.

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.

The present disclosure concerns the production of precursor compounds for lithium battery cathodes. Batteries or their scrap are smelted in reducing conditions, thereby forming an alloy suitable for further hydrometallurgical refining, and a slag. The alloy is leached in acidic conditions, producing a Ni- and Co-bearing solution, which is refined. The refining steps are greatly simplified as most elements susceptible to interfere with the refining steps concentrate in the slag. Metals such as Co, Ni and Mn are then precipitated from the solution, forming a suitable starting product for the synthesis of new battery precursor compounds.

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.

It is provided a process for recycling lithium ion batteries comprising shredding the lithium-ion batteries and immersing residues in an organic solvent; feeding the shredded batteries residues in a dryer producing a gaseous organic phase and dried batteries residues; feeding the dried batteries residues to a magnetic separator removing magnetic particles; grinding the non-magnetic batteries residues; mixing the fine particles and an acid producing a metal oxides slurry and leaching said metal oxides slurry; filtering the leachate removing the non-leachable metals; feeding the leachate into a sulfide precipitation tank; neutralizing the leachate; mixing the leachate with an organic extraction solvent; separating cobalt and manganese from the leachate using solvent extraction and electrolysis; crystallizing sodium sulfate from the aqueous phase; adding sodium carbonate to the liquor and heating up the sodium carbonate and the liquor producing a precipitate of lithium carbonate; and drying and recuperating the lithium carbonate.

Disclosed is a method for anaerobically cracking a power battery, which includes the following steps: disassembling a waste power battery to obtain a battery cell; taking out a diaphragm from the battery cell for later use, and pyrolyzing the battery cell to obtain electrode powder; extracting nickel, cobalt and manganese elements from the electrode powder with an extraction buffer, filtering, taking the filtrate, then adjusting the filtrate with a nickel solution, a cobalt solution and a manganese solution to obtain a solution A, adding the solution A dropwise into ammonium hydroxide under stirring, and then adding an alkali solution under stirring to obtain a solution B; subjecting the solution B to a hydrothermal reaction, filtering, and roasting to obtain a catalyst, such that a chemical formula of the catalyst is Ni.sup.2+.sub.1-x-yCo.sup.2+.sub.xMn.sup.2+.sub.yO, where 0.25≤x<0.45, 0.25≤y<0.45.
