Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT The similar physicochemical properties of alkali metal elements make the co‐enrichment and precise separation of Cs+ and Rb+ in complex brine systems highly challenging. Here, an all‐inorganic strategy is proposed, which achieves efficient enrichment and precise separation of Cs+ and Rb+ in high‐salt systems by constructing Sr2+/Ba2+‐based ...

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.

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT CsPbI3 quantum dots (QDs) have attracted considerable attention as promising candidates for light‐emitting diode (LED) applications. However, their intrinsic tendency to undergo a spontaneous phase transition to a nonperovskite structure significantly hampers their practical deployment. Considerable efforts have been devoted to stabilizing the
