Iridium Oxide Inverse Opal Anodes with Tailored Porosity for Efficient PEM Electrolysis

Advanced Functional Materials, EarlyView.
The synthesis of Iridium‐based Inverse Opals (Ir‐IO) is reported as electrocatalyst for Proton exchange membrane water electrolysis (PEM‐WE). Using the developed protocol it produces highly porous materials consisting either of metallic, oxidic Iridium or a combination thereof with large surface areas.

Deciphering a New Electrolyte Formulation for Intelligent Modulation of Thermal Runaway to Improve the Safety of Lithium‐Ion Batteries

Advanced Functional Materials, EarlyView.
Diels‐Alder clicks chemistry addresses thermal runaway in lithium‐ion batteries. A thermoresponsive electrolyte with lithium salt in vinylene carbonate (VC) and 2,5‐dimethylfuran (DMFu) operates at room temperature but undergoes Diels‐Alder reactions at high temperatures, enabling a two‐step safety mechanism: a warning phase at ≈100 °C and complete ...
