The 1,2-diethoxyethane (DEE) molecule promotes the moderate Na+-DEE coordination, thus leading to the uniform and inorganic-rich solid electrolyte interphase, as proved by the cryogenic electron microscopy characterizations. Consequently, the Na metal anode is highly stable in the NaPF6/DEE-based electrolyte with a high Coulombic efficiency of 99.9 % and dendrite-free deposition behavior.

揭示溶剂对钠金属电池固体电解质界面形成的影响
低温电子显微镜表征证明，1,2-二乙氧基乙烷（DEE）分子促进适度的Na + -DEE配位，从而形成均匀且富含无机物的固体电解质界面。因此，Na金属阳极在NaPF 6 /DEE基电解质中高度稳定，具有99.9%的高库仑效率和无枝晶沉积行为。
