Bi‐Functional Diaminopropane Additive Enables Stable Li Anodes and Highly Efficient Cathodes for High‐Performance Li‐Air Batteries

open access: yesAdvanced Science, EarlyView.
Diaminopropane (DAP) solvent is employed as a bi‐functional additive for Li‐air batteries. It spontaneously reacts to form a gel layer to prevent corrosion on the Li anode and maintain a liquid state at the cathode to improve the decomposition of Li2O2.

Unveiling the Corrosion Mechanisms of High‐Entropy RETaO4 Through In Situ Observation

open access: yesAdvanced Science, EarlyView.
Composition‐property relationships in multi‐component RETaO4 are unveiled. In situ XRD/TEM and EBSD expose dynamic crystallization pathways of the dominant corrosion product (pyrochlore) and reaction‐diffusion corrosion mechanisms. La1/6Nd1/6Sm1/6Eu1/6Gd1/6Dy1/6TaO4 emerges as the optimal composition, combining minimal corrosion layer thickness with ...
