Functionalized Organic Lithium Salt Enables Flexible Solid‐State Electrolytes With Dual‐Ion Channels for Safe Li Metal Batteries

open access: yesCarbon Energy, EarlyView.
Here, we design a flexible and non‐flammable solid‐state electrolyte with hierarchical dual‐ion conductive channels. The engineered electrolyte combines continuous organic conductive‐phase pathways for fast bulk Li+ transport and dynamic polymer networks for interfacial ion hopping, achieving unprecedented room temperature conductivity (> 1 mS cm−1 ...

High‐Performance Solid‐State Lithium Batteries via Dipole‐Matching: Enabling Compact Polymer Microstructure and Stable Interfaces

open access: yesCarbon Energy, EarlyView.
A dipole–matching strategy is proposed to engineer PVDF‐HFP solid polymer electrolytes by incorporating 3,5–bis(trifluoromethyl)benzoic acid. Dipole interactions regulate polymer nucleation and phase alignment, forming compact microstructures, while controlled FSI– decomposition induces a LiF–rich interphase, enabling fast Li+ transport, uniform ...

Passive Moisture‐Driven Cooling via Low‐Cost and Shape‐Stabilized Hygroscopic Composite Foam for High‐Power Electronics

open access: yesCarbon Energy, EarlyView.
A passive moisture‐driven cooling strategy is proposed to effectively manage the heat in high‐power electronic and energy devices, reducing the chip temperature by 37°C, the lithium‐ion battery temperature by 26°C, and the photovoltaic panel temperature by 15°C, thereby to enhance the battery safety and PV efficiency with a low‐cost, shape‐stabilized ...

Influence of Particle Size, Moisture, and Cloud Density on Wood Dust Ignition

open access: yesChemie Ingenieur Technik, EarlyView.
The ignition and combustion of particle clouds are strongly affected by particle interactions. This study uses spectroscopy to examine effects of particle size, water content, and cloud density. Results show ignition delay rises with larger size and density, whereas combustion duration depends mainly on water and density due to moisture‐driven ...
