Li2VFeS4
metal· JVASP-113758· Li2VFeS4
Li₂VFeS₄ is a mixed-metal sulfide compound combining lithium, vanadium, and iron—a research-phase material being investigated for energy storage and electrochemical applications. This compound belongs to the family of multivalent metal sulfides and is primarily of interest in battery research, particularly for lithium-ion and post-lithium battery chemistries where vanadium and iron redox activity can enable high energy density. The material is notable as an experimental cathode or conversion-type anode candidate because it leverages multiple electrochemically active metals to improve capacity and cycling performance compared to conventional single-metal oxides or sulfides.
