Nanostructured Optical Superabsorbers from Carbon Nanotube Forest for Heat Management Using Environmental Blackbody Radiation from the Visible to Mid‐Infrared

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Our computational model of the optical absorption from multiwalled carbon nanotubes suggests the optical absorption depends strongly on the in‐plane electrical conductivity, and weakly on the through‐plane conductivity. Such strong absorption enables solar‐to‐thermal conversion for heat scavenging in cold climates and radiative cooling in hot climates,

Anion‐Synergistic Regulation of Solvation‐Layer Chemistry in Nonflammable Electrolytes Enables Highly Safe and Durable Sodium Metal Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study establishes a new anion‐synergistic solvation chemistry framework for directing interfacial reactions and stabilizing sodium metal anodes. Uncontrolled dendrite growth, accompanied by thermal runaway in sodium metal, remains a critical bottleneck for practical applications of sodium metal batteries (SMBs).

Harnessing Thin‐Film Solid‐State Electrolytes: Enabling Breakthroughs in All‐Solid‐State Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Schematic illustration highlighting the advantages of transitioning from traditional thick solid‐state electrolytes (SSEs) to thin‐film SSEs. Thinning the electrolyte enables higher ionic conductivity, reduced interfacial polarization, improved flexibility, compact electrode contact, and enhanced energy density, offering a promising pathway toward high‐
