· JVASP-46919· Li7CoOF7

Li7CoOF7 is an oxyfluoride ceramic compound combining lithium, cobalt, oxygen, and fluorine—a composition category of interest for solid-state electrochemistry and energy storage research. This material belongs to the family of lithium-containing ceramics being explored for solid electrolytes and cathode materials in advanced battery systems, where the mixed anion framework (oxide + fluoride) can provide improved ionic conductivity and electrochemical stability compared to conventional oxide ceramics alone.

Regulatory Screening

Environmental

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.
