Ultrathin Li Metal Anodes: Quantitative Design Principles and Manufacturability Across Liquid and Solid‐State Batteries

Advanced Materials, EarlyView.
Ultrathin lithium metal anodes (≤15 µm) offer a promising route to high‐energy‐density batteries due to their high capacity and low potential. This review presents design principles for ultrathin Li, evaluates fabrication strategies, and discusses challenges in liquid and solid‐state cells.

An Analysis on the Overvoltage in Gas Insulated Transmission Lines with EMTP/ATPDraw

The Transactions of The Korean Institute of Electrical Engineers, 2011
Nowadays, it is becoming difficult to secure a transmission line route when a new transmission line is constructed due to social environment and resident complaints. As existing urban areas are expanded and new cities are constructed, the necessity of high-capacity underground power transmission has been increasing because of load concentration in ...

All‐Polyimide‐Mediated Liquid Metal Assembly on Aerogels for Breathable and Robust Electronic Skins

Advanced Materials, EarlyView.
An all‐polyimide‐mediated assembly strategy resolves the fundamental conflict between physiological breathability and electromechanical robustness in wearable electronics. By integrating a polyamic acid‐encapsulated liquid metal ink onto an ultralight polyimide aerogel, imidization‐induced contraction enables low‐temperature conductive activation and ...

Engineering CO2 Reduction Pathways via Alloy‐Support Interactions in Li‐CO2 Batteries

Advanced Materials, EarlyView.
Alloy‐support interactions in RuCu/NC induce interfacial charge redistribution and shift d‐band centers, steering CO2 reduction from Li2CO3 to metastable Li2C2O4. This pathway engineering lowers the rate‐determining barrier and suppresses carbonate formation, enabling high discharge voltage (3.23 V) in Li‐CO2 batteries with reduced overpotential (0.50 ...

Atomic Layer Deposition of Metallic Molybdenum Dioxide Thin Films Enabling High‐k Rutile Capacitors

Advanced Materials Interfaces, EarlyView.
The first direct atomic layer deposition (ALD) process of molybdenum dioxide (MoO2) thin films is reported using molybdenum(II) acetate dimer (Mo2(OAc)4) and oxygen (O2) as precursors at 235°C–275°C. The films are crystalline, exceptionally pure, and conductive.
