Rare Metals, EarlyView.ABSTRACT Aqueous zinc‐ion batteries (AZIBs) hold great promise for safe and sustainable energy storage, but their commercialization is impeded by severe Zn dendrite growth and interfacial instability. To address these challenges, we propose a defect engineering strategy employing ultrafine ZnAl2O4 (ZAO) nanoparticles (∼5 nm) with oxygen vacancy defects

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Low conductivity and poor oxygen reduction reaction (ORR) catalytic activity limit the bifunctional catalytic performance of layered double hydroxide (LDH) in zinc–air batteries. In this work, an efficient bifunctional electrocatalyst was prepared by loading nitrogen and phosphorus co‐doped carbon quantum dots (NPCQDs) onto a cationic‐vacancy ...

Porous Mn2O3@C Cathode With High Activity and Long Lifespan for Aqueous Zinc Ion Batteries
Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Manganese‐based oxides are widely employed as cathode materials for aqueous zinc ion batteries (AZIBs) due to their low toxicity and high theoretical specific capacity. However, their inherent poor electrical conductivity, coupled with the dissolution of manganese into the electrolyte, often leads to structural degradation of the cathode.
