Dual‐Layer Solid Electrolyte Interphase Enables Effective Suppression of Lithium Dendrites
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The heterogeneous solid electrolyte interphase (SEI) at the Li metal anode often leads to slow and uneven Li+ flux, causing severe Li dendrite growth. Herein, we combine X‐ray photoelectron spectroscopy and cryogenic transmission electron microscopy to demonstrate that a dual‐layer SEI, consisting of an inorganic inner layer and an organic ...

Flexible, Robust Transparent Conductive Films With Excellent Electromagnetic Shielding Properties
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Transparent conductive films (TCFs) are indispensable components for next‐generation wearable electronics, intelligent robots, and electromagnetic interference (EMI) shielding devices. However, the fabrication of conventional random metallic mesh suffers from an inherent trade‐off between “randomness and controllability”.

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Solar‐blind ultraviolet (UV) photodetectors (SBPDs) play a critical role in applications including UV communication and fire warning systems. Gallium oxide (Ga2O3) has emerged as a promising material due to its wide bandgap and low cost, but suffers from high dark current and slow response speed caused by oxygen vacancy (VO) defects. This work
