摘要： In a method for recovering lithium hydroxide from a lithium secondary battery, cathode powder is prepared from a cathode of the lithium secondary battery. A cathode active material mixture is prepared by mixing the cathode powder with a calcium compound. The cathode active material mixture is reduced to form a preliminary precursor mixture. A lithium precursor is recovered from the preliminary precursor mixture. Therefore, a lithium precursor can be obtained with high purity without a complicated leaching process or an additional process, which result from a wet-based acid solution process.

摘要： A method for producing lithium hydroxide that allows reducing a load of removing divalent or more ions with an ion-exchange resin is provided. The method for producing lithium hydroxide includes steps (1) to (3) below. (1) a neutralization step: a step of adding an alkali to a first lithium chloride containing liquid to obtain a post-neutralization liquid, (2) an ion-exchange step: a step of bringing the post-neutralization liquid into contact with an ion-exchange resin to obtain a second lithium chloride containing liquid, and (3) a conversion step: a step of electrodialyzing the second lithium chloride containing liquid to obtain a lithium hydroxide containing liquid. Since this producing method allows roughly removing divalent or more ions in the neutralization step, a load of metal removal with the ion-exchange resin is reducible.

摘要： Provided herein are processes for recovering lithium ions from a brine source. The process can comprises increasing the pH of a brine source comprising lithium ions to at least about 5.5; contacting the pH-elevated brine source with a bed of protonated ion exchange media to produce a lithiated ion exchange media and a lithium-depleted brine stream; contacting the lithiated ion exchange media with an acidic aqueous wash liquid; and contacting the washed lithiated ion exchange media with an elution liquid comprising an acid. Also provided herein is a process for increasing the pH of brine comprising obtaining brine from a brine source comprising lithium ions; adding the brine to a continuously stirred tank reactor without preprocessing the brine to remove solid matter; adding a strong base to the continuously stirred tank reactor; contacting the brine with the base. Further provided herein are processes for creating a lithiated ion exchange media, which can comprise contacting a pH-elevated brine source with a bed of protonated ion exchange media; and producing a lithiated ion exchange media and a spent brine, wherein the bed of protonated ion exchange media comprises a metal oxide absorbent and a polymeric binder.

摘要： In this disclosure, a process of recycling acid, base and the salt reagents required in the Li recovery process is introduced. A membrane electrolysis cell which incorporates an oxygen depolarized cathode is implemented to generate the required chemicals onsite. The system can utilize a portion of the salar brine or other lithium-containing brine or solid waste to generate hydrochloric or sulfuric acid, sodium hydroxide and carbonate salts. Simultaneous generation of acid and base allows for taking advantage of both chemicals during the conventional Li recovery from brines and mineral rocks. The desalinated water can also be used for the washing steps on the recovery process or returned into the evaporation ponds. The method also can be used for the direct conversion of lithium salts to the high value LiOH product. The method does not produce any solid effluent which makes it easy-to-adopt for use in existing industrial Li recovery plants.

摘要： Compositions suitable for reversibly storing heat in thermal energy systems (TES) include a salt hydrate represented by the formula: MXq.nH2O. M is a cation selected from Groups 1 to 14 of the IUPAC Periodic Table, X is a halide of Group 17, q ranges from 1 to 4, and n ranges from 1 to 12. The cation (M) may have an electronegativity of ≤ about 1.8 and a molar mass ≤ about 28 g/mol. The anion (X) may have an electronegativity of ≥ about 2.9 to ≤ about 3.2. A distance between a cation (M) and coordinating water molecules (H2O) is ≤ about 2.1 Å. Thermal energy systems (TES) incorporating such compositions are also provided that are configured to reversibly store heat in the thermal energy system (TES) via an endothermic dehydration reaction and to release heat in in the thermal energy system (TES) via an exothermic hydration reaction.
