Silicified Wood‐Inspired, High‐Strength Fire‐Resistant Chitin‐Based Aerogels for Sustainable High‐Temperature Thermal Insulation

Advanced Functional Materials, EarlyView.
Inspired by natural silicified wood, a biomimetic mineralized chitin‐derived aerogel is constructed. It can withstand 81 000 times its own weight, and its backside temperature is 130.4°C after exposure to ∼1300°C butane flame for 600 s, exhibiting high‐strength, fire‐resistance, and super thermal‐insulation properties.

Dynamic Proton Activity Regulation via Brønsted Bases Enables Durable and High‐Energy‐Density Zn||MnO2 Batteries

Advanced Functional Materials, EarlyView.
Our study demonstrates Brønsted base‐mediated proton transfer for HOAc dissociation regulation in weakly acidic electrolytes, where imidazole achieves optimal dynamic proton equilibrium‐simultaneously stabilizing Zn anodes and enabling efficient Mn2+/MnO2 conversion.

Formation of Quasi‐Decoupling Interface on Li‐Metal Anodes in High Donor Electrolyte

Advanced Functional Materials, EarlyView.
Li‐metal anode (LMA) is stabilized by introducing Li2Te2 as an electrolyte additive for Li‐metal batteries. Upon contact with Li, Li2Te2 spontaneously converts to Li2Te, which electronically isolates Li from dimethyl sulfoxide due to its large bandgap and minimal Bader charge transfer.
