· JVASP-48157· LiVP2O7

Lithium vanadium pyrophosphate (LiVP₂O₇) is an inorganic ceramic compound belonging to the class of lithium-transition metal phosphates. This material is primarily investigated in battery research contexts, particularly as a potential cathode or electrode material for lithium-ion and solid-state battery systems, where its layered phosphate structure and mixed-valence vanadium chemistry offer opportunities for lithium-ion transport and electrochemical cycling. Compared to conventional oxide cathodes, vanadium pyrophosphates are explored for their thermal stability, structural flexibility, and potential to achieve competitive energy density in alternative battery chemistries, though widespread commercial adoption remains limited and most applications remain in the research and development phase.
