Synergistic Crystallinity Reduction and Lewis Acidic Promotion by PVDF‐Al(OH)3 for High Room‐Temperature Ionic Conductivity in PEO‐Based Composite Quasi‐Solid Electrolytes

EcoEnergy, EarlyView.
Through the synergistic effects of crystallinity reduction and Lewis acidic promotion enabled by PVDF‐Al(OH)3, a PEO‐based composite quasi‐solid electrolyte has been developed, achieving both a high Li+ transfer number and superior ionic conductivity. It endows lithium metal batteries with excellent cycling stability at room temperature, even without ...

Thermoresponsive Gel Polymer Electrolytes Enabled by Retained Double Bonds for Thermal Shutdown in Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A smart gel electrolyte with thermal shutdown capability has been proposed enabled by a two‐step cross‐linking strategy, which preserves a high density of unreacted double bonds at room temperature. This strategy brings negligible degradation to room temperature electrochemical performance, while under thermal abuse conditions above 115 °C, the gel ...

Char Layer Thickness Evolution During Structural Timber Fire Experiment and Final Density Profile

Fire and Materials, EarlyView.
ABSTRACT This paper evaluates several non‐destructive experimental methods for determining the char layer thickness and its density profile in structural timber samples exposed to standard ISO 834 fire curve experiments. Microwave echo pulse, ultrasonic echo pulse, X‐ray computed tomography, and resistance drilling were evaluated.

HRR–Time Behaviour of Untreated Wood Under SBI Conditions: Implications for the Interpretation of FIGRA and THR600

Fire and Materials, EarlyView.
ABSTRACT Reaction‐to‐fire classification of wood‐based materials in Europe relies on SBI‐derived parameters such as FIGRA and THR600. While these parameters provide a robust and practical basis for classification, their relationship to the underlying HRR–time development remains difficult to interpret.
