Simultaneously, electrons flow through an external circuit. During charging, the process is reversed, with F- ions moving back to the cathode. The key components of an FIB include: a cathode material capable of intercalating and deintercalating F- ions, an anode material which serves as a fluoride ion reservoir, a solid electrolyte to enable F- ion transport, and current collectors to facilitate electron flow. The solid electrolyte must be highly conductive to F- ions while also being electronically insulating to prevent short circuits. Furthermore, the materials used must be chemically stable and compatible to ensure long-term battery performance and safety. The efficiency of the battery relies heavily on the properties of the solid electrolyte and the efficiency of the redox reactions at both electrodes. Research continues on improving the materials and design to increase energy density and cycle life, as well as to address challenges such as the limited availability of suitable solid-state electrolytes with high fluoride conductivity.
