Abstract

Disclosed is a process for coating onto a substrate, including preparing a precursor having a general formula QMOFby a reaction M(OH)+yHF+m/nQ(OH)→Q(MOF), wherein Q is an onium ion, selected from quaternary alkyl ammonium, quaternary alkyl phosphonium and trialkylsulfonium; M is a metal capable of forming an oxofluorometallate, where M may further comprise one or more additional metal, metalloid, and one or more of phosphorus (P), sulfur (S) and selenium (Se), iodine (I), and arsenic (As) or a combination thereof, and x>0, y>0, m≥1, n≥1; combining the precursor with a lithium ion source and with the substrate, and mixing to form a coating composition comprising a lithium oxofluorometallate having a general formula LiMOFon the substrate. Further disclosed is a core-shell electrode active material including a core capable of intercalating and deintercalating lithium coated with the lithium oxofluorometallate having the general formula LiMOF.
