Li2 V3 Fe1 O8

Li2V3Fe1O8 is a mixed-valence oxide ceramic compound combining lithium, vanadium, and iron in a single framework structure. This material is primarily investigated in battery and electrochemistry research contexts, particularly as a potential cathode material for lithium-ion batteries where the vanadium and iron redox couples enable charge storage and discharge cycling. Engineers consider this compound family for energy storage applications where high volumetric capacity, cycling stability, and cost-reduction through iron doping are development priorities, though it remains largely in the research phase compared to conventional cathode materials like LCO or NMC.
