· Li4 V2 O2 F6

Li₄V₂O₂F₆ is a mixed-anion lithium vanadium oxide fluoride compound belonging to the family of advanced lithium-ion cathode materials and solid-state electrolyte candidates. This is a research-phase material being investigated for next-generation energy storage systems where the combined oxygen and fluoride ligands offer potential improvements in electrochemical stability, ionic conductivity, and structural robustness compared to conventional oxide-only cathodes. Engineers would consider this compound where high energy density, thermal stability, or fast lithium-ion transport is critical, though commercial adoption remains limited pending further development and scale-up feasibility.
