Li2 Ag2 F4

Li₂Ag₂F₄ is an ionic semiconductor compound combining lithium, silver, and fluorine, belonging to the family of mixed-metal fluorides. This is a research-phase material studied primarily for its potential in solid-state electrolytes and ion-conducting applications, where the combination of lithium and silver cations offers promising fast-ion transport characteristics. The material's appeal lies in enabling next-generation solid-state batteries and electrolyte systems where high ionic conductivity at moderate temperatures is critical, though it remains largely in academic development rather than high-volume industrial use.
