title: Synthesis of Ca(PF6)2, formed via nitrosonium oxidation of calcium.
abstract: The development of rechargeable Ca-ion batteries as an alternative to Li systems has been limited by the availability of suitable electrolyte salts. We present the synthesis of complexes of Ca(PF6)2(a key potential Ca battery electrolyte salt) via the treatment of Ca metal with NOPF6, and explore their conversion to species containing PO2F2-under the reaction conditions.
