Abstract
NaPO<sub>2</sub>F<sub>2</sub> prepared <italic>via</italic> a facile two-step reaction was characterized by structural analysis and used as an additive for sodium-ion batteries. The addition of NaPO<sub>2</sub>F<sub>2</sub> formed a highly Na<sup>+</sup>-conductive SEI layer, which enhanced electrode performance.
