Abstract Viability of room-temperature rechargeable in-situ sodium plated batteries (INPBs) with bare Cu current collector foil as anode is reported which operated by sodium plating-stripping on Cu foil during each charge-discharge cycle, respectively. Using 1M NaBF4 in tetraglyme electrolyte, an Na2Fe2(CN)6//Cu INPB delivered 336 Wh/kg specific energy density with 76% retention in 100 cycles.
