Sodium (Na)-ion batteries have been considered as one of the most promising power sources beyond Li-ion batteries. Although Na metal anode exhibits a high theoretical capacity of 1165 mAh g-1, its application on Na batteries is largely hindered by dendrite growth and low Coulombic efficiency. Herein, we demonstrate that an electrolyte consists of 1 M sodium tetrafluoroborate in Tetraglyme can enable excellent cycling efficiency (99.9 %) of Na metal anode for more than 1000 cycles. This high reversibility of Na anode can be attributed to a stable solid electrolyte interphase formed on Na surface as revealed by cryogenic transmission electron microscopy and X-ray photoelectron spectroscopy. These electrolytes also enabled excellent cycling stability of Na||hard carbon cells and Na||Na2/3Co1/3Mn2/3O2 cells at high rate with very high coulombic efficiencies.
