Resistance Drift of Phase Change Materials Beyond the Power Law

open access: yesAdvanced Electronic Materials, EarlyView.
The timedependent resistance of phase change materials is important for their application as electronic memory. Here, resistance measurements of melt‐quenched germanium telluride from nanoseconds to minutes are presented. By going far beyond the usually considered measurement regime, deviations from the ubiquitous power law behavior are observed, that ...

Enhancing Thermoelectric Performance of Cd₃P₂ by Alloying with Dirac Material Cd₃As₂

open access: yesAdvanced Electronic Materials, EarlyView.
This study demonstrates that alloying Cd₃P₂ with Dirac material Cd₃As₂ significantly enhances its thermoelectric performance. Key improvements include increased carrier mobility, reduced effective mass, and lower deformation potential, resulting in a doubled power factor and improved thermoelectric efficiency, which renders this material applicable for

Sulfonated Polystyrene/Polybenzimidazole Bilayer Membranes for Vanadium Redox Flow Batteries

open access: yesAdvanced Energy Materials, EarlyView.
PBI‐coated sulfonated polystyrene membranes are prepared, and the performance of the various possible assemblies of two such membranes is tested. A 52 µm thick PSSP assembly can be fabricated with a materials cost of just 1.84 USD m−2, and shows an energy efficiency of 89.7% at 80 mA cm−2.

Sulfonated para‐Polybenzimidazole Membranes for Use in Vanadium Redox Flow Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Dense sulfonated para‐PBI membranes (MS‐PBI) are tested in the VRFB. The conductivity is 10 times lower than reported for MS‐PBI gel membranes, but 10 times higher than that of meta‐PBI. The influence of membrane preparation process, thickness, and operating temperature on the VRFB performance is investigated.

Polyphenylene‐Based Anion Exchange Membranes with Robust Hydrophobic Components Designed for High‐Performance and Durable Anion Exchange Membrane Water Electrolyzers Using Non‐PGM Anode Catalysts

open access: yesAdvanced Energy Materials, EarlyView.
Terphenyl groups bearing meta‐phenylene and trifluoromethyl substituents as hydrophobic components are incorporated into a quaternized polyphenylene‐based backbone to produce AEMs. The fabricated thin membranes exhibit high ion conductivity, alkaline stability, and mechanical robustness.
