Microstructure Evolution in Dry‑Coated Sulfidic All‐Solid‐State Battery Cathodes: Investigating Core–Shell Particle Morphology

Advanced Science, EarlyView.
Mixing method directly governs interface engineering and electrode morphology during the dry coating of all‐solid‐state battery cathodes. While high‐shear batch mixing yields poor electrode quality and lacks core–shell‐like features, continuous extruder mixing enables strong binder fibrillation and a core–shell‐like coating between the active material ...

Hydrogen Production from Ammonia Electrochemical Cracking

Advanced Science, EarlyView.
NH3 electrochemical cracking (e‐cracking) is a complementary technique to centralized thermal cracking for releasing H2 from NH3. In this article, we review recent advances in catalyst development for these cracking techniques and conduct a techno‐economic analysis (TEA) to evaluate the economic feasibility of e‐cracking.

Dual‐Functional Membranes With Interfacial MXene/PFSA Nanoarchitectures for Low Hydrogen Permeation in Water Electrolysis and Reduced Vanadium Ion Crossover in Flow Batteries

Advanced Science, EarlyView.
A PFSA/MXene composite membrane is developed for both PEMWE and VRFB applications. MXene incorporation simultaneously enhances proton conductivity and suppresses hydrogen/vanadium crossover. The interaction between MXene functional groups and PFSA's –SO3H reduces the proton diffusion barrier via hydrogen‐bonding networks, while the disordered ...
