Emerging High‐Entropy Electrolytes for High‐Performance Alkali Metal Batteries: Mechanism, Progress, and Prospects

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Alkali metal (Li, Na, and K) batteries (AMBs) have attracted widespread attention in recent years because of their high theoretical specific capacity and attractive energy density. However, they still suffer from uncontrollable dendrite growth and sluggish conductivity during cycling, which lead to security issues and inferior cycling ...

Abnormal Phase Transition Mechanism in the CoCrAlY Bond Coat Revealed by In Situ and Ex Situ Experiments

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT In Co‐based alloys, the γ phase is normally stable at high temperatures and the ε phase at low temperatures, and there is a martensitic transition on cooling to ∼417°C. In the γ/β dual‐phase CoCrAlY bond coat of turbine blade thermal barrier coating systems, we observed the opposite: γ remained stable at room temperature, yet it underwent a γ →
