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

Systems and methods are disclosed for enhancing the construction and application of batteries by providing a battery system comprising at least one electrochemical panel with at least one electrochemical cell disposed therein, which is configured to enable multi-purpose functionality and applicability of the battery system. Embodiments provide for electrodes and/or current collectors of each electrochemical cell that are transversely orientated with respect to each face of an electrochemical panel. Some embodiments provide for a separator pouch disposed about at least one electrode and/or current collector to electrically insulate the electrode and/or current collector from a structure component of the device. Each electrochemical panel is configured to enable electrical communication with another electrochemical panel and/or an ancillary electric circuit. Each electrochemical panel is configured enable utilization thereof as a structural component of an ancillary structure.
