Bidirectional Interfacial Chemical Regulation Enables Durable Aqueous Zn‐I2 Batteries
ABSTRACT Aqueous Zn‐I2 batteries hold great promise for large‐scale energy storage, yet their practical deployment is hindered by coupled interfacial instabilities at both electrodes, where Zn‐anode parasitic reactions and cathodic polyiodide shuttle mutually aggravate each other.

ABSTRACT Non‐noble metal oxygen electrocatalysts are essential for low‐cost rechargeable metal‐air batteries and fuel cells, determining their energy conversion efficiency. However, such electrocatalysts are limited by inadequate bifunctional activity and stability toward the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER).

ABSTRACT Sodium‐ion batteries (SIBs) offer a promising, cost‐effective alternative for large‐scale energy storage due to the abundance of sodium. However, their practical deployment is challenged by sluggish interfacial kinetics and unstable interphase formation, which severely limit performance across wide temperature ranges. Here, we demonstrate that
