Sodium‐Ion and Polyaniline Co‐Intercalation into Ammonium Vanadate Nanoarrays Induced Enlarged Interlayer Spacing as High‐Capacity and Stable Cathodes for Flexible Aqueous Zinc‐Ion Batteries

Vanadate oxides with low price and high theoretical capacity are competitive cathodes for aqueous zinc‐ion batteries (AZIBs). However, the existing problems such as sluggish Zn2+ ion mobility, weak conductivity, and complicated flexible electrode preparation hinder the development of their practical...
