NaFeF3 Nanoplates as Low-Cost Sodium and Lithium
Here, we report a simple synthetic route for crystalline NaFeF 3 NPLs through the thermal decomposition of heterometallic, fluorinated, β-diketonate NaFe(hfac) 3 in benzyl ether or 1-octadecene (ODE) with oleic acid (OAc) and oleylamine (OAm) as ligands. We determined that the NaFeF 3 NPLs exhibit a high cyclic stability as cathode materials in both sodium and lithium ion batteries .
