Synergistic Design of Composite Ionogels With Enhanced Thermoelectric Properties, Mechanical Stretchability, and Sustainable Recyclability

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
While flexible TE devices hold promise for converting low‐grade waste heat (e.g., from human skin or electronics) into usable electricity, existing materials suffer from three major limitations: 1) poor mechanical stretchability (failing to match human skin's elongation, ~20–30%), limiting wearability; 2) tradeoffs between thermoelectric efficiency (e ...

In Situ Bilayer Interphase Enables Air‐Stable Li Metal Anode for Long‐Term Li‐Air Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
An in situ formed bilayer SEI—featuring an Ag/LiF‐enriched inner backbone and a CF3‐dominated hydrophobic outer shell—enables fast/uniform Li+ transport and exceptional moisture‐air stability for Li metal. Lithium metal is an attractive anode for next‐generation high‐energy batteries, but its practical use is plagued by dendrite growth and parasitic ...
