Regulating Hybrid Na <sup>+</sup> /Zn <sup>2+</sup> ‐Ion Acetonitrile‐Water Electrolyte Enables High Rate and Long‐Life Na <sub>3</sub> V <sub>2</sub>
Na 3 V 2 (PO 4 ) 3 (Na 3 VP) is an attractive cathode for rechargeable aqueous zinc‐ion batteries (RAZBs). Yet it suffers from inferior cycling stability and rate performance in aqueous electrolytes due to structural degradation, dissolution and sluggish transport of guest cations. To tackle these issues...
