Anion-mediated approach to overcome oxidation in ether electrolytes for high-voltage sodium-ion batteries

In a proof-of-concept study, we selected extensively studied G2 electrolytes to serve as the typical mode for our analysis. To evaluate high-voltage stability, we employed a P3-phase Na_2/3Ni_1/2Mn_1/2O₂ (NNM) electrode material with a particulate…
