IMMOBILIZED SELENIUM, A METHOD OF MAKING, AND USES OF IMMOBILIZED SELENIUM IN A RECHARGEABLE BATTERY
Publication number: 20220407049Abstract: 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.Type: ApplicationFiled: August 31, 2022Publication date: December 22, 2022Inventors: Elgin E.

Publication number: 20200070665Abstract: A charging station including a “reservoir” energy supply is proposed. The reservoir supply is formed of one or more rapid charge/discharge batteries that are also able to hold their charge for an extended period of time (as compared to conventional supercapacitors, for example). The reservoir supply is contemplated to accommodate transient increases in power demand when a given charging station has to re-charge several vehicles (for example) at the same time. The rechargeable batteries forming the reservoir are advantageously configured to thereafter be re-charged at a fast rate as well, making them ideal candidates for re-charging from secondary sources (such as, but not limited to, solar, fuel cells, wind, and the like).Type: ApplicationFiled: August 28, 2018Publication date: March 5, 2020Applicant: II-VI Delaware, Inc.Inventors: Shailesh Patkar, Yancheng Zhang, Giovanni Barbarossa, Wen-Qing Xu, Christopher Koeppen, Elgin Eissler
