A Solvent‐Free, Dry‐Processed Li‐Ion Battery Enabled by Dual Binders and Nanostructured Aluminum Current Collectors

open access: yesAdvanced Functional Materials, EarlyView.
A dual‐binder dry‐processed electrode (DB‐DPE) combining PTFE and PVDF with a nanostructured Al current collector (NSA) forms a mechanically interlocked interface that significantly improves adhesion and reduces interfacial resistance. With an active material content as high as 96 wt.%, the NSA‐based DB‐DPE enables high‐mass‐loading operation (12.5 mAh

Solvent‐Free Bonding Mechanisms and Microstructure Engineering in Dry Electrode Technology for Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Dry electrode technology revolutionizes battery manufacturing by eliminating toxic solvents and energy‐intensive drying. This work details two promising techniques: dry spray deposition and polymer fibrillation. How their unique solvent‐free bonding mechanisms create uniform microstructures for thicker, denser electrodes, boosting energy density and ...

Low-mass Stars: Their Protoplanetary Disk Lifetime Distribution

open access: yesThe Astrophysical Journal
While most protoplanetary disks lose their gas within less than 10 Myr, individual disk lifetimes vary from 5 Myr. The next challenge is to quantitatively link the diversity of disk lifetimes to the diversity in planets.

‘Oxygen Bound to Magnesium’ as High Voltage Redox Center Causes Sloping of the Potential Profile in Mg‐Doped Layered Oxides for Na‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Na‐ion batteries ‐ Impact of doping on the oxygen redox: The sloping potential of NaMg0.1Ni0.4Mn0.5O2 above 4.0 V is caused by a new redox center (arising from the ‘O bound to Mg’), having a higher potential but being more irreversible compared to the ‘O bound to Ni’.

Chemistry of Complex Organic Molecules in the V883 Ori Disk Revealed by ALMA Band 3 Observations

open access: yesThe Astronomical Journal
Complex organic molecules (COMs) in protoplanetary disks are key to understanding the origin of volatiles in comets in our solar system, yet the chemistry of COMs in protoplanetary disks remains poorly understood.

Self‐Reconstruction of Dual‐Morphology Copper‐Iron Selenides for Cost‐Effective Oxygen Evolution Toward Industrial Alkaline Water Splitting

open access: yesAdvanced Functional Materials, EarlyView.
Departing from conventional Ni/Co‐based catalysts, this work presents a Ni/Co‐free CuFe–Se/CFF electrocatalyst with nanoblock–nanorod morphology. It delivers 1000 mA cm−2 at 330 mV overpotential and 620 h stability for the oxygen evolution reaction (OER).
