Self‐Adaptive Gradient Interphase Enables Durable Solid‐State Lithium Metal Batteries

Advanced Functional Materials, EarlyView.
This work presents a machine learning‐guided interfacial design that forms a self‐adaptive graded interphase on lithium metal anode. A B105M40 composite interlayer evolves into lithiophilic, porous, and fast‐ion‐conducting phases, enabling intimate contact, dendrite suppression, and uniform lithium deposition.

Highly Efficient and Stable Roll‐to‐Roll Coated Perovskite Solar Cells Enabled by Antisolvent Vapor‐Assisted Crystallization

Advanced Functional Materials, EarlyView.
Antisolvent Vapour‐Assisted Crystallization (AVAC) enables controlled perovskite crystallization through precisely metered antisolvent vapour, eliminating liquid antisolvent waste. Compatible with roll‐to‐roll (R2R) slot‐die coating, AVAC produces uniform, pinhole‐free films with enlarged grains, delivering efficiencies of 18.3% for R2R fabricated ...
