· K2 Ni1 F4

K2Ni1F4 is a layered fluoride compound belonging to the Ruddlesden-Popper family of materials, characterized by corner-sharing nickel fluoride octahedra separated by potassium cation layers. This is a research-stage material studied for potential ionic conductivity and electrochemical applications; compounds in this structural family are investigated as solid electrolytes and electrode materials for advanced battery systems, though K2Ni1F4 itself remains largely in the exploratory phase rather than commercial production.

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.
