· Li2 Fe4 F14

Li₂Fe₄F₁₄ is a lithium iron fluoride compound belonging to the fluoride semiconductor family, potentially relevant to solid-state electrochemistry and energy storage research. This material exists primarily as a research compound rather than a commercial product; it is investigated for applications in lithium-ion battery systems, solid electrolytes, and related electrochemical devices where fluoride-based ionic conductors offer advantages in thermal stability and charge carrier mobility. Compared to conventional oxide-based ceramics in these domains, fluoride compounds like this can provide improved electrochemical windows and lower activation energies for ion transport, making them of interest to battery researchers developing next-generation energy storage systems.
