High‐Performing Perovskite/Ruddlesden‐Popper Fuel Electrode for High‐Temperature Steam Electrolysis

open access: yesAdvanced Energy Materials, EarlyView.
By combining perovskite and Ruddlesden‐Popper phases, a Ni‐free fuel electrode with exceptional electrocatalytic activity and ionic conductivity is developed. This approach minimizes polarization resistance, achieving 0.053 Ω cm2 at 800 °C and 1.084 W cm−2 power density.

Ammonia Synthesis at Room Temperature and Atmospheric Pressure from N2: A Boron‐Radical Approach

open access: yesAngewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023
Boron‐centered radicals, generated by reduction of R2BCl derivatives, react with N2 all the way to borylamine formation. DFT calculations rationalize the reduction/functionalization process, involving N−N bond splitting. Hydrolysis of the mixture yields NH4+. Radical addition to N2 provides a new strategy for N2 fixation.

Enabling High‐Voltage Polymer‐Based Solid‐State Batteries Through Reinforcements with LiAlO2 Fillers

open access: yesAdvanced Energy Materials, EarlyView.
Polymer‐ceramic solid composite electrolytes with passive LiAlO2 fillers show remarkable improvements in Li‐ion conductivity in polycarbonates as compared to both non‐conductive Al2O3 and conductive Li7La3Zr2O12 counterparts. The exceptionally high transference numbers contribute to reversible and stable electrochemistry with Li‐metal electrodes and to

Quantifying the Impact of Cathode Composite Mixing Quality on Active Mass Utilization and Reproducibility of Solid‐State Battery Cells

open access: yesAdvanced Energy Materials, EarlyView.
The origin of variations in solid‐state battery cell performance is explored and traced back mainly to the cathode composite mixing – leading to different fractions of electrochemically active mass. Machine‐mixed composites and the quantification of the electrochemically active mass enhance reproducibility and comparability.

Boon and Bane of Local Solid State Chemistry on the Performance of LSM‐Based Solid Oxide Electrolysis Cells

open access: yesAdvanced Energy Materials, EarlyView.
Cation diffusion causes an increase in the catalytically active MIEC region in solid oxide cells. Simultaneously, it leads to the additional formation and growth of secondary structures in the electrolyte, which reduces the oxygen diffusion. Abstract High‐temperature solid oxide cells are highly efficient energy converters.
