Li4 Ti4 Fe4 O16

Li₄Ti₄Fe₄O₁₆ is a mixed-metal oxide semiconductor belonging to the lithium titanate family, combining lithium, titanium, and iron cations in a crystalline oxide framework. This compound is primarily of research and development interest for energy storage and electrochemical applications, where the iron substitution in the lithium titanate structure is explored to enhance electronic conductivity and modify electrochemical performance compared to pure Li₄Ti₅O₁₂ spinel materials. Engineers considering this material should recognize it as an emerging candidate for next-generation lithium-ion battery anodes and solid-state electrolyte systems rather than an established commercial product.
