Impact of Transition Metals and Electrocatalyst Layer Thickness on the Pt‐Based Cathodes of Proton Exchange Membrane Fuel Cells – Do Multimetallic Electrocatalysts Necessarily Yield an Improved Performance?

Advanced Energy Materials, EarlyView.
Nonnoble transition‐metals (TMs) in PtCuNi/C catalysts have a dual influence in proton‐exchange membrane fuel cell cathode catalyst layer. While TMs act as a “sacrificial component” of PtCuNi/C, inhibiting Pt dissolution from the PtMx nanoparticles bearing the active sites, they promote the formation of separate catalysts and ionomer domains in the ...

Stretchable Energy Storage with Eutectic Gallium Indium Alloy

Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
A highly stretchable liquid metal‐based electrode is developed via a one‐step process, retaining conductivity and capacitance after mechanical deformation up to 900% strain. The stretchable all‐solid‐state device provides a areal energy density of 43 µWh cm⁻2 after 150% strain.

Confining Surface Oxygen Redox in Double Perovskites for Enhanced Oxygen Evolution Reaction Activity and Stability

Advanced Energy Materials, EarlyView.
The double perovskite BaSrNiWO6 is developed as an oxygen evolution reaction catalyst. B‐site W6+ dissolution drives in situ reconstruction of the surface to a disordered, NiO‐like layer. Consequently, local oxygen species are activated for a surface lattice oxygen evolution mechanism (sLOEM).

Understanding Structural and Compositional Evolution during NMC Cathode Direct Recycling via Solid‐State NMR

Advanced Energy Materials, EarlyView.
Direct recycling end‐of‐life lithium‐ion batteries (LIB) to recover high‐value cathode materials such as LiNixMnyCozO2 (NMC) requires method development and detailed characterization. In this work, the unique capabilities of solid‐state NMR in characterizing changes in local ordering within NMC cathode materials during recycling and upcycling as well ...
