摘      要：NASICON-(Na superionic conductor-)based solid-state electrolytes(SSEs)are believed to be attracting candidates for solid-state sodium batteries due to their high ionic conductivity and prospectively reliable ***,the poor interface compatibility and the formation of Na dendrites inhibit their practical ***,we directly observed the propagation of Na dendrites through NASICON-based Na3.1Zr2Si2.1P0.9O12 SSE for the first ***,a fluorinated amorphous carbon(FAC)interfacial layer on the ceramic surface was simply developed by in situ carbonization of PVDF to improve the compatibility between Na metal and ***,Na dendrites were effectively suppressed due to the formation of NaF in the interface when molten Na metal contacts with the FAC *** from the optimized interface,both the Na||Na symmetric cells and Na3V2(PO4)3||Na solidstate sodium batteries deliver remarkably electrochemical *** results offer benign reference to the maturation of NASICON-based solid-state sodium batteries.
