Redox Behavior of a CuF_2/Cu Electrode for an All-Solid-State Fluoride Shuttle Battery

摘要

The popularization of electrified vehicles connected to the smart grid community systems with stationary energy storage has attracted much attention as one of the solutions to global environmental problems. The critical technologies for such systems are rechargeable batteries with energy densities higher than that of conventional Li-ion batteries (LIBs). Among various candidates, all-solid-state fluoride-ion batteries (FIBs) operated by fluoride-ion transport are promising owing to an ultrahigh theoretical energy density over 5000 Wh/L.
