Leveraging Digital Advanced Manufacturing to Enable Polymer Electrolyte Fuel Cells With Ultrahigh Gravimetric Power Density

Advanced Energy Materials, EarlyView.
This study employs digital advanced manufacturing to develop lightweight, compact porous distributors as alternatives to conventional bipolar plates in PEM fuel cells. A graphene‐coated nickel foam achieves a power density of 1.52 W cm−2, while titanium‐based designs deliver lightweight solutions: an LPBF‐fabricated Gyroid lattice reaches 1.36 W cm−2 ...

From Materials to Systems: Challenges and Solutions for Fast‐Charge/Discharge Na‐Ion Batteries

Advanced Energy Materials, EarlyView.
This review systematically analyzes the key characteristics limiting the fast‐charge/discharge capability of Na‐ion batteries (SIBs) from a multi‐scale perspective encompassing electrode materials, the electrode‐electrolyte interface, and the system. Furthermore, it presents practical solution strategies for the fundamental issues arising at each scale,

Dendrite Formation and Self‐Healing Mechanism in Ionic Liquid‐Based Magnesium Batteries

Advanced Energy Materials, EarlyView.
This graphical illustration highlights the importance of operating Mg batteries within a safe operating current density (SOCD) range. Beyond this range, Mg batteries are susceptible to dendrite formation. However, when cycling a dendritic cell with a highly thermally stable electrolyte, a self‐heating effect occurs.

Thin Reinforced Sulfonated Poly(phenylene sulfone) Membranes for Durable Water Electrolysis: Suppressed Swelling and Enhanced Stability Over 2000 Hours

Advanced Energy Materials, EarlyView.
Hydrocarbon membranes have the potential to significantly enhance the efficiency of water electrolyzers. However, their application is often limited by insufficient stability resulting from excessive swelling. This work presents a strategy to achieve efficient, safe and stable operation of a 24 µm thin hydrocarbon membrane by combining a modified ...

Degradation Mechanisms of Rutile‐Type TiO2 Photoanodes during Photoelectrochemical Water Splitting

Advanced Energy Materials, EarlyView.
Combining operando dissolution measurements with microscopy and spectroscopy characterizations, we reveal different degradation mechanisms of rutile‐type TiO2 photoanodes during photoelectrochemical water splitting. In acidic electrolytes, degradation is inhibited once TiO2 reaches saturation.
