· 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.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
