Orbital and Electrical Dual Function of Polymer Intercalant for Promoting NH4+ Storage in Vanadium Oxide Anode (Adv. Energy Mater. 11/2025)

Ammonium-Ion Storage

In article number 2404732, Zihang Huang, Xu Han, Tianyi Ma, and co-workers fabricated a polyaniline-intercalated vanadium oxide material, and systematically investigated atomic orbital and electronic structure variations induced by polyaniline. The insertion of polyaniline promotes electrons transition, leading to enhanced electrical conductivity. These synergistic effects facilitate NH⁴⁺ transfer, thereby enhancing the stability of aqueous devices and demonstrating significant potential for high-performance applications.
