Gas Sensing With Aerogels: A Critical Review on Structure‐Property Correlations and Performance Optimization

Advanced Science, EarlyView.
With high specific surface area, and adjustable interface, aerogel provides a multi‐functional platform for gas sensing. This review systematically links structural parameters (specific surface area, pore size, heterojunctions) to sensing metrics (sensitivity, selectivity, stability), critically evaluates optimization strategies, and outlines future ...

Green and Low‐Carbon Synthesis of Lithium Sulfide (Li2S): From Fundamental Mechanisms to Scalable Manufacturing for Next‐Generation Energy Storage

Advanced Science, EarlyView.
This review focuses on green synthesis routes for lithium sulfide (Li2S)—a key material for lithium–sulfur batteries and sulfide solid electrolytes, whose traditional carbothermal reduction remains energy‐intensive and unsustainable. Specifically examined routes include low‐temperature solid‐state reactions, magnesiothermal reduction, and solution ...

Hydrogen‐Bond Enabled Phosphite Based Intrinsic Flame‐Retardant Solid‐Solid Phase Change Materials Using Catalyst/Solvent‐Free Multi‐Component Reaction for Battery Thermal Management

Advanced Science, EarlyView.
The phosphite group endows intrinsic flame retardancy, while the P = O bond enhances intermolecular interactions to realize solid‐solid phase transition. Battery thermal management tests show the materials extend the safe working time of lithium‐ion batteries by 200%. Cone calorimeter tests indicate a 14s delay in ignition time, and reductions of 37.6%,
