Li4 Ti3 Fe3 Ni2 O16

Li₄Ti₃Fe₃Ni₂O₁₆ is a complex mixed-metal oxide ceramic compound combining lithium, transition metals (iron and nickel), and titanium in a structured lattice. This is a research-phase material investigated primarily for energy storage and electrochemical applications, where the multi-valent transition metal composition and lithium content position it as a candidate for battery electrode materials or solid-state electrolyte components. Its appeal lies in potential cost advantages (iron and nickel are more abundant than cobalt) and tunable electrochemical properties, though it remains largely confined to laboratory development rather than commercial production.
