Durable Lithium Metal Anodes Enabled by {110}‐Textured Epitaxy on a LiF@Ag Commensurate Heterostructure

Advanced Science, EarlyView.
Utilizing their commensurate lattices, a LiF@Ag heterostructure is fabricated for Li epitaxy, featuring Ag nanoparticles grown on 2D LiF layers. The composition pinning effect inhibits Li‐Ag alloying and maintains the high lithiophilicity and fast adatom migration associated with Ag.

Dual‐Ligand Strategy in Rh‐Catalyzed Sequential Hydrofunctionalization of Valylene

Advanced Science, EarlyView.
A remarkable dual‐ligand strategy is employed in Rh‐catalyzed sequential coupling reaction of dinucleophiles and 1,3‐enynes with high regio‐ and chemo‐selectivity. Abstract Controlling regio‐ and chemo‐selectivity in transition‐metal‐catalyzed reactions involving coupling reagents with multiple reactive sites remains a significant challenge.

Heterogeneity of the Dominant Causes of Performance Loss in End‐of‐Life Cathodes and Their Consequences for Direct Recycling

Advanced Energy Materials, EarlyView.
Direct recyling of Li‐ion battery materials promises a low‐cost path towards a secure domestic supply of critical materials for batteries. Using cathode material from an end‐of‐life commercial Li‐ion cell, this work identifies the primary degradation mechanisms that diminish the performance of directly reused cathode materials and includes a discussion

A Novel Quantification Method for High Voltage Structural Evolution in Sodium and Lithium Layered Oxides

Advanced Energy Materials, EarlyView.
High‐voltage cycling of layered alkali transition metal oxides in Li‐ and Na‐ion cells increases energy density but diminishes lifetime. A novel XRD‐analysis method, centered on the stacking factor “z”, is developed to quantify the stacking fractions in the OP hybrid structure.
