Linking DSC/TGA to Cell Levels: Energetics, Evolved Gases, and Thermal Safety of NMC811‐Graphite Micro‐Cell

open access: yesAdvanced Energy Materials, EarlyView.
A bottom‐up, component‐resolved framework combining DSC/TGA, evolved gas analysis, and in situ XRD reveals how decomposition pathways control energy release in partial and micro‐cell configurations. Separator‐free assemblies are dominated by cathode‐O2${\rm O}_2$/anode‐Li reactions, while the separator restricts oxygen transport, reshapes the reaction ...

Design Guidelines for Anode Modifications to Eliminate Soft Short Circuits in Anode‐Free Na Batteries Under High Current Density With Large‐Capacity Plating, Demonstrated via Initiated Chemical Vapor Deposition (iCVD)

open access: yesAngewandte Chemie, EarlyView.
This work establishes a laterally homogeneous organic–inorganic hybrid interphase for soft‐short‐free anode‐free sodium metal batteries under extended cycling at high current density and high plating capacity. In contrast to conventional strategies that evolve into laterally heterogeneous interphases and induce localized Na filament growth, the pDFHA ...

Tracking Dynamic Sulfur Electrochemistry by Operando Techniques in Alkali Metal‐Sulfur Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Dynamic sulfur electrochemistry in alkali metal‐sulfur batteries is tracked through operando spectroscopy, scattering, imaging, and modelling. This Review connects sulfur reaction pathways, polysulfide transport, electrolyte/interphase evolution, anode chemistry, and quantitative mechanistic analysis across Li‐S, Na‐S, and K‐S batteries, providing ...

Glyoxylic‐Acetal‐Based Gel‐Polymer Electrolytes for Lithium‐Ion Batteries

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
A safe electrolyte based on tetraethoxyglyoxal (LE) is combined with a methacrylate polymer matrix. The resulting gel‐polymer electrolyte (GPE) exhibits an increased flash point, suitable ionic conductivity, and a stable performance in lithium‐ion battery cells.

Investigation of Electrolyte Salts in Non‐Flammable Triethyl Phosphate for Sodium‐Ion Batteries

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
This study evaluates five sodium electrolyte salts (NaBF₄, NaClO₄, NaDFOB, NaFSI, NaPF₆) in triethyl phosphate (TEP) for sodium‐ion full‐cells, focusing on their physicochemical properties, solvation structure, and electrochemical performance. The addition of 1 wt.% vinylene carbonate (VC) improves cycling performance, with NaFSI demonstrating 88 ...

Amorphous Protective Layers to Reshape Inorganic‐Rich Interphases for High‐Voltage Sodium‐Ion Batteries

open access: yesCarbon Energy, EarlyView.
Herein, we propose a straightforward and efficacious strategy of surface modification for P2‐type Na0.7Li0.03Mg0.03Ni0.27Mn0.6Ti0.07O2 cathode in high‐voltage Na‐ion batteries. The stable amorphous SiO2 coating layer on the cathode surface contributes to a strong, dense, fluorine and silicon‐rich cathode–electrolyte interphase, which inhibits the side ...
