摘要： The present disclosure belongs to the field of lithium ion battery recovery and discloses a method for selectively recovering valuable metals in waste lithium batteries. The method includes the following steps: adding a sulfur-containing compound to waste lithium battery for calcination and water leaching to obtain lithium carbonate solution and filter residue; adding sulfuric acid and an iron-containing compound to the filter residue for leaching, performing solid-liquid separation, and taking solid phase to obtain manganese dioxide and graphite residue; extracting and reverse extracting liquid phase from the solid-liquid separation to obtain nickel cobalt sulfate solution and manganese sulfate solution. The method of the present disclosure selectively extracts lithium in waste ternary cathode materials by calcination and water leaching, and realizes selective low manganese leaching based on the principle that divalent manganese can reduce the high oxide of nickel and cobalt in the leaching stage.

摘要： The principal approaches to reducing the effects of global warming seek to slow the increase in atmospheric CO2 levels as a result of fossil fuel combustion for energy production and transportation. A process for hybrid carbon capture and mineralization are disclosed. The process utilizes both flue gas from (e.g., power plants) and reject brine from (e.g., desalination process). The process includes providing flue gas to react with an amine solution to produce carbamate; processing the carbamate in a reactor to regenerate amine and to produce a carbonate; treating reject brine to provide a ready-made brine for carbonation reaction; and processing the carbamate with salt from treating the brine to produce a carbonate.

摘要： Methods for recycling lithium and iron containing material, such as batteries, include selectively leaching lithium from the material by disposing the material in a powder form in a solution comprising formic acid and hydrogen peroxide, filtering the solution to obtain a first leach liquor comprising lithium and a residue comprising iron phosphate and carbon, subjecting the first leach liquor to a first precipitation to remove residual iron from the leach liquor and obtain a second leach liquor, and subjecting the second leach liquor to a second precipitation, wherein lithium is precipitated and a third leach liquor is obtained. The third leach liquor may be subjected to a third precipitation using trisodium phosphate or sodium carbonate. The material may be a battery cathode, such as a lithium iron phosphate battery cathode.

摘要： The presently disclosed concepts relate to improved techniques for critical mineral extraction, purification, precipitation, ion exchange, and metal production using a solid electrolyte membrane. By using a solid electrolyte embedded in a matrix, alkali metal (such as lithium) can be more effectively separated from feed solutions. Additionally, energy used to initially extract critical minerals from a feed solution may be stored as electrochemical energy, which in turn, may be discharged when critical minerals are depleted from the electrode. This discharged energy may therefore be reclaimed and reused to extract additional critical minerals.

摘要： This document describes a method for reducing the corrosivity of certain magnesium salts. The salt product resulting from the method exhibits reduced corrosion of steels that come into contact with the salt relative to salt compositions that are not so treated. This makes such treated salts more efficient coolant salts as they will require less equipment replacement over time. The method uses magnesium metal to reduce unwanted impurities in the salts the reduced impurities are then removed as either gas or precipitate from the now purified salt. Without being bound to one particular theory, it is believed that the reduction of the level of impurities in the salt results in a salt with substantially reduced corrosiveness to steel.

摘要： Integrated Energy Systems (IESs), such as for use in capturing atmospheric carbon dioxide, and associated devices and methods are described herein. A representative IES can include a power plant system having multiple modular nuclear reactors, a desalination plant, a brine processing plant, and a direct air capture plant. The nuclear reactors can generate electricity and/or steam for use by the desalination plant and the direct air capture plant. The desalination plant can use the electricity and/or steam to produce brine from seawater or brackish water. The brine processing plant can receive the brine from the desalination plant and process the brine to produce sodium hydroxide. The direct air capture plant can use the sodium hydroxide as a liquid sorbent in a direct air capture process to capture carbon dioxide from atmospheric air.
