Breaking the Durability–Power Trade‐Off: Boron‐Directed Faceted O3 Cathodes for High‐Rate Sodium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Boron‐oxide‐assisted particle engineering stabilizes O3‐type layered cathodes for sodium‐ion batteries by mitigating phase transitions and lattice strain. Acting as flux and structural modifier, boron forms submicron hexagonal platelets with (003) facets and expanded Na‐layer spacing, enabling rapid Na⁺ diffusion and mechanical resilience.

Beyond Imperfect Match: Silicon/Graphite Hybrid Anodes for High‐Energy–Density Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Silicon/graphite (Si/Gr) hybrid anodes are limited by Si's large volume change and mismatch with Gr. This review offers mechanistic insights into imperfectly matched Si/Gr hybrid anodes, elucidating heterogeneous lithiation behavior and interfacial failure pathways, and thereby informing the design of durable, high‐energy–density lithium‐ion batteries.

Experimental Isolation of Single Impact, Cumulative Energy, Aging, and Liquid‐Assisted Grinding Effects in Mechanochemical Reactions

open access: yesAngewandte Chemie, EarlyView.
An experimental framework is introduced to isolate single‐impact and cumulative energy within a mechanochemical system. The guided, stepwise approach highlights the fundamental roles of impact events, post‐impact reactivity, and liquid‐assisted grinding additives in all‐solid mechanochemical reactions.

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

open access: yesAdvanced 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 ...

Engineering Na‐Rich P2‐Type Layered Oxides Through Li/Ti Dual Doping for Oxygen Redox Activation and Superior Structural Stability

open access: yesAdvanced Energy Materials, EarlyView.
P2‐type sodium layered oxides have potential for high‐voltage operation but suffer from structural instability and capacity fading. This work demonstrates that synergistic Li and Ti co‐doping enhances sodium inventory, suppresses detrimental phase transitions, and activates reversible lattice oxygen redox.

Low‐Temperature Reverse Water–Gas Shift Enabled by Magnetically Induced Catalysis

open access: yesAngewandte Chemie, EarlyView.
Magnetically induced catalysis using standard Cu–Al spinel‐derived catalyst functionalized with carbon‐coated iron nanoparticles enables high CO yield (up to 62%) at mild catalyst and reactor temperatures (estimated at 300°C and determined as 25–123°C, respectively).

The milling of pristine and brominated P-100 graphite fibers [PDF]

open access: yes
Techniques were developed for the ball milling of pristine and brominated P-100 graphite fibers. Because of the lubrication properties of graphite, large ball loads (50 percent by volume) were required.
