Resumen de: WO2024091623A1
A method and system for producing a release layer on a carrier film is provided. The release layer is produced through direct fluorination processing of the carrier film prior to deposition of an alkali metal such as lithium. The carrier film is then laminated with a desired anode. The fluorine-based release layer allows efficient release of the deposited lithium from the carrier film after lamination while preventing contamination of the metallic lithium from outgassing by the carrier film. The release layer allows the carrier film to be configured for reuse minimizing hazardous waste and improving cost-efficiency. The carrier film may also be provided with a second fluorinated layer on the back end of the carrier film. This allows the carrier film to also be preserved.
Resumen de: WO2024091574A1
A battery architecture based on the inclusion of a solid polymer electrolyte (SPE) as a safer alternative to that of liquid electrolytes. The construction of the battery enables the battery device to store energy not only electrochemically, but also electrostatically through an electric double-layer capacitance formed by the charge separation on the interface between the electrolyte and electrodes. This architecture allows the storage of additional energy, thus exceeding the theoretical specific capacity of a conventional Li metal battery. An interfacial therapy was modified to improve Li metal stability, and to enhance mass transport at the electrolyte/anode interface.
