High‐Rate Magnesium‐Ion Batteries Enabled by Boron‐Doped Bismuth Anodes

Large volume expansion upon (de)alloying faced by bismuth anodes always leads to severe capacity loss and poor durability for magnesium‐ion batteries. This failure mode becomes particularly pronounced under high current‐density impact, where the sluggish electron transport and io...

From scrap to prime: Designing high-performance alloys from dirty feedstocks with machine learning

Producing alloys from recycled metals via secondary synthesis can markedly cut energy use, greenhouse-gas emissions, and dependence on scarce, strategically important elements relative to primary routes. The central obstacle is the feedstock itself: Scrap is chemically heterogene...

High‐Purity Hydrogen Production From Water–Gas Shift Reaction in a High‐Temperature Polymer Electrolyte Membrane Electrolyzer

ABSTRACT The water–gas shift reaction (WGSR) is a critical pathway for hydrogen production, yet current methods face trade‐offs between purity and scale. Thermocatalytic WGSR achieves high product purity but requires energy‐intensive gas separation, while room‐temperature electro...

Application Progress of hydrogels in aqueous zinc batteries

Aqueous zinc-ion batteries (AZIBs) have emerged as highly promising candidates for next-generation flexible energy storage, driven by the intrinsic safety, earth-abundance, low cost, and exceptional volumetric capacity of metallic zinc. However, the widespread application of trad...
