CrOF3

Chromium oxyfluoride (CrOF₃) is an inorganic ceramic compound combining chromium, oxygen, and fluorine—a mixed-anion system that imparts unique electrochemical and structural properties distinct from simple oxides or fluorides. This material is primarily investigated in research contexts for energy storage applications, particularly as a cathode material in fluoride-ion batteries and advanced electrochemical systems, where the fluoride component enables higher voltage operation and the chromium redox activity provides charge capacity. Compared to conventional lithium-ion cathodes, CrOF₃-family materials offer potential for higher energy density and alternative ion-transport mechanisms, making them relevant for next-generation battery development where cobalt-free and high-performance alternatives are sought.
