A Family of Sodium Solid‐State Electrolytes Based on the NaGaxAl1‐xCl4 Solid Solution

Advanced Materials Interfaces, EarlyView.
ABSTRACT Sodium‐based metal chloride solid electrolytes are promising for sodium solid‐state batteries due to their excellent oxidation stability, which, as shown for Li halides, can coexist with high ionic conductivity. To explore cationic substitution effects, we synthesized NaGaxAl1‐xCl4 (0 ≤ x ≤ 1) via ball milling and investigated structural and ...

Impact of PVDF Homo and Copolymer on Thiophosphate Solid Electrolyte Characteristics and Comprehensive Bulk‐To‐Surface Characterization

Advanced Materials Interfaces, EarlyView.
This study examines how a PVDF‐like binder affects the argyrodite Li6PS5Cl electrolyte properties. Using an approach that combines bulk and surface characterization with electrochemistry, we found a chemical interaction between Li6PS5Cl and PVDF, resulting in partial chlorine substitution by fluorine and slightly reduced ionic conductivity.

Pyrolysis Induced Interphase and Structural Stabilization of Silicon‐Tin Disulfide/PAN Composite Electrode Materials for Li‐Ion Batteries

Advanced Materials Interfaces, EarlyView.
A Si and SnS2 based dual‐alloy anode material for metal‐ion battery applications with improved structural, interfacial and electrochemical properties is synthesized via a single‐step solid‐state pyrolysis process. During the pyrolysis step, SnS2 and Si are embedded in a porous, carbonized PAN‐based matrix, which is electronically and ionically ...

Light Switchable Ionic Conductivity of Arylazopyrazole Modified Polysiloxanes

Advanced Materials Technologies, EarlyView.
We present a polysiloxane functionalized with a novel arylazopyrazole dye that undergoes reversible photoisomerization. Upon lithium bis(trifluoromethanesulfonyl)imide addition and UV irradiation, the polymer exhibits a shift in tan(d) toward higher frequencies and enhanced ionic conductivity.

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

The Influence of Mesoscale Particle Structure on the Electrode Degradation and Resultant Electrochemistry of Lithium Ion Cells With Nickel Rich Lithium Nickel Manganese Cobalt Oxide Positive Electrodes

Advanced Materials Technologies, EarlyView.
Milled polycrystalline NMC811 cathode (MPC NMC) with smaller secondary particle and higher surface area had 1) greater cathode tortuosity, 2) reduced surface Ni on the cycled MPC cathodes consistent with surface reconstruction, and 3) increased Ni deposition from cathode‐anode crosstalk, manifesting in lower functional capacity and higher impedance ...
