Li12Fe5O16

Li12Fe5O16 is an iron-lithium oxide ceramic compound belonging to the spinel or mixed-oxide family, of primary interest as a research material rather than an established commercial product. This composition is investigated for energy storage, particularly in lithium-ion battery cathode materials and solid-state electrolyte applications, where lithium mobility and iron redox chemistry offer potential advantages in charge capacity and thermal stability. The material represents exploratory work in advanced battery chemistries where engineers evaluate unconventional lithium-iron oxide phases to improve energy density, cycle life, or safety compared to conventional layered oxides or phosphate-based cathodes.
