An immobilized chalcogen system or body includes a mixture or combination of chalcogen and carbon. The carbon can be in the form of a carbon skeleton. The chalcogen can include oxygen, sulfur, selenium, or tellurium, or a combination of any two or more of oxygen, sulfur, selenium, and tellurium. The activation energy for chalcogen to escape the immobilized chalcogen system or body is ≥96 kJ/mole.

Immobilized chalcogen and use thereof in a rechargeable battery

An immobilized selenium body, made from carbon and selenium and optionally sulfur, makes selenium more stable, requiring a higher temperature or an increase in kinetic energy for selenium to escape from the immobilized selenium body and enter a gas system, as compared to selenium alone. Immobilized selenium localized in a carbon skeleton can be utilized in a rechargeable battery. Immobilization of the selenium can impart compression stress on both the carbon skeleton and the selenium. Such compression stress enhances the electrical conductivity in the carbon skeleton and among the selenium particles and creates an interface for electrons to be delivered and or harvested in use of the battery. A rechargeable battery made from immobilized selenium can be charged or discharged at a faster rate over conventional batteries and can demonstrate excellent cycling stability.

Immobilized selenium, a method of making, and uses of immobilized selenium in a rechargeable battery

In a method of preparing an immobilized selenium system or body, a selenium-carbon-oxygen mixture is formed. The mixture is then heated to a temperature above the melting temperature of selenium and the heated mixture is then cooled to ambient or room temperature, thereby forming the immobilized selenium system or body.

An immobilized chalcogen system or body includes a mixture or combination of chalcogen and carbon. The carbon can be in the form of a carbon skeleton. The chalcogen can include oxygen, sulfur, selenium, or tellurium, or a combination of any two or more of oxygen, sulfur, selenium, and tellurium. The activation energy for chalcogen to escape the immobilized chalcogen system or body is &#x2265;96 kJ/mole.

A composite extractant-enhanced polymer resin comprising an extractant and a polymer resin for direct extraction of valuable metals such as rare earth metals, and more specifically, scandium, from an acid-leaching slurry and/or acid-leaching solution in which ferric ions are not required to be reduced into ferrous ions. The extractant may be cationic, non-ionic, or anionic. More specifically, the extractant di(2-ethylhexyl)phosphoric acid may be used. The polymer resin may be non-functional or have functional groups of sulfonic acid, carboxylic acid, iminodiacetic acid, phosphoric acid, or amines. The composite extractant-enhanced polymer resin may be used for extraction of rare earth metals from acid-leaching slurries or solutions.

Composite extractant-enhanced polymer resin, method of making the same, and its usage for extraction of valuable metal(s)

A method for extracting rare earth metals from an acidic slurry or an acidic solution. The method includes providing an acidic slurry or acidic solution; adding a composite comprising an extractant and a polymer resin; mixing the composite with the acidic slurry or acidic solution to form a mixture slurry or solution; and separating the mixture slurry or solution into a rare-earth-metal-loaded composite and a raffinate slurry or solution. The acidic slurry or acidic solution comprises at least one rare earth metal and at least one early transition metal and/or at least one actinide metal.
