Inert Copper Incorporation Enables the High Activity and Durability of NiW Electrocatalyst for Alkaline Hydrogen Oxidation Reaction

open access: yesAdvanced Energy Materials, EarlyView.
Cu incorporation further refined the binding strength for intermediates (H* and OH*). Therefore, the resulting Cui‐NiW exhibited outstanding HOR activity, yielding a peak power density of 340 mW cm−2 in a noble metal‐free fuel cell. Moreover, the alloy demonstrated robust durability with only a 5.7% current drop after 10000 cycles.

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

open access: yesAdvanced Energy Materials, Volume 15, Issue 16, April 22, 2025.
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.

Sustainable Recovery and Reuse of Hard Carbon From Scrap and End‐of‐Life Sodium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
As sodium‐ion battery (SIB) technology advances, sustainable end‐of‐life recycling is crucial. This study presents a direct recycling method for hard carbon (HC) using low‐temperature binder negation at 300 °C under nitrogen. Retaining structural integrity, recycled HC achieves 86–89% capacity retention over 200 cycles.
