摘要: 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.

摘要: An immobilized chalcogen system or body includes an element of chalcogen, an electrically conductive material, and a hydrophilic membrane gate. The hydrophilic membrane gate may be used to isolate hydrophobic regions, one related to polychalcogenide ion(s) and another related to a hydrophobic electrolyte system. The hydrophilic membrane gate may prevent polychalcogenide from forming, and may provide control of undesirable parasitic mass transport and undesirable electron transport inside a chalcogen-based battery, and thereby allow the battery to cycle at a high specific capacity with a long cycling life. If desired, the immobilized chalcogen system or body may be employed in a cathode of a rechargeable battery.

摘要: 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.

摘要: 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.
