Triple‐Coupling Regulation Enables Dendrite‐Free Subzero Aqueous Zn‐Ion Batteries

Advanced Science, EarlyView.
A formamide‐ethanol deep eutectic electrolyte enables triple‐coupling regulation of solvation structure, interfacial chemistry, and crystallographic Zn deposition. The reconstructed Zn2+ solvation reduces water activity and suppresses side reactions, while a robust hybrid SEI stabilizes the interface.

Toward Practical Zn‐Ion Batteries Through Separator/Electrolyte Co‐Design

Advanced Science, EarlyView.
A hybrid organic–aqueous electrolyte enables thin commercial polypropylene separators to replace bulky glass‐fiber separators in practical Zn‐ion batteries. This electrolyte/separator co‐design improves wettability, promotes uniform Zn plating/stripping, and suppresses hydrogen evolution, resulting in 4360 h of symmetric‐cell cycling and stable Zn//NVO

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.

Electrocatalytic reduction of simulated industrial CO2 and CO mixtures: revising chronoamperometry to enable selective gas mixture reduction via cyclic voltammetry

While substantial advancements have been achieved in the electrocatalytic reduction of pure CO2 or CO, the reduction of carbon oxide mixtures remains underexplored, a key limitation in scaling the technology for industrial applications.
