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.

高能量密度在-原位钠镀电池用集电体箔作为阳极

室温可再充电的存活力在-原位与裸铜集电体箔钠镀电池（PBS中），其阳极被报道了通过电镀剥离分别各充放电循环过程中的Cu箔，钠操作。在四甘醇二甲醚电解质中使用1M NaBF ₄时，Na ₂ Fe ₂（CN）₆ // Cu INPB可提供336 Wh / kg的比能密度，并在100个循环中保留76％的能量。
