KMnF₃ is a metal fluoride compound belonging to the perovskite family, combining potassium, manganese, and fluorine in a structured ceramic-metallic framework. This material remains primarily in the research domain, investigated for its potential in energy storage systems (particularly as a cathode material for fluoride-ion batteries) and as a functional ceramic in high-temperature or chemically aggressive environments where fluoride stability is advantageous. Its notable characteristics stem from the strong Mn-F bonding and three-dimensional lattice structure, which researchers explore for electrochemical applications where conventional oxide materials show limitations.
