Metastable Structure for Ultra‐Sustainable, High Capacity and Kinetics‐Enhanced Magnesium‐Ion Battery

Advanced Science, EarlyView.
A metastable‐phase evolution strategy is proposed for magnesium‐ion batteries, enabling the in situ formation of a metastable MgxT‐VS4 cathode during cycling. The metastable state reshapes Mg2+ storage kinetics and enhances structural stability, offering a new design paradigm for multivalent ion battery cathodes.

Experimental Observation of a Calcium Silicon Double Carbonate

Angewandte Chemie, EarlyView.
High‐pressure and ‐temperature reactions between Ca5(Si2O7)(CO3)2 tilleyite and CO2 carbon dioxide yield the first experimental evidence of the double carbonate Ca2Si(CO3)4 and a new Ca2(C4O10) phase containing tetrahedral [CO4] units. These findings reveal unexpected carbonate chemistry and highlight pathways for carbon incorporation under mantle ...

Towards Climate Neutrality by 2050: Role of Aluminum for Short‐ and Long‐Term Energy and Hydrogen Storage

Advanced Energy Materials, EarlyView.
The Aluminum energy storage cycle involves the use of renewable energy for Al production and the generation of heat (dry cycle) and heat and H2 (wet cycle) for energy production via Al‐steam combustion. ABSTRACT Reaching climate neutrality by 2050 requires innovative long‐term energy storage (LTES) solutions beyond the current use of fossil fuels ...

A Guideline to Evaluate Sorbent Performance for Atmospheric Water Harvesting

Advanced Energy and Sustainability Research, EarlyView.
Reporting guidelines for atmospheric water harvesting sorbents allow benchmarking between research groups across seven key performance indicators (KPIs). Beyond simple equilibrium values (such as capacity or maximum water uptake), these KPIs validate sensitivity, reversibility, regeneration conditions, chemical stability, kinetics, and water quality ...
