The Dynamics of Interfacial Trap States in High‐Detectivity Near‐Infrared Photomultiplication Organic Photodetectors

Advanced Functional Materials, EarlyView.
Photomultiplication organic photodetectors (PM OPDs) are an attractive strategy for health‐monitoring. Here, PM‐OPDs are reported with a specific detectivity of 5.7 × 1012 Jones and external quantum efficiency values of 3500% under −10 V. The dynamics of carrier trapping in these devices are elucidated through trap selective spectroscopical techniques.

Coordinated Multi‐Component Gradient Engineering of Catalyst Layers for Advanced Polymer Electrolyte Fuel Cells

Advanced Functional Materials, EarlyView.
This work presents a continuous linear gradient catalyst layer design, a general strategy for improving membrane electrode assemblies across electrochemical devices. Fabricated via a dual‐nozzle spray coating method, the architecture controls the Pt/carbon ratio, ionomer content and ionomer type across the catalyst layer, enhancing proton conduction ...

Analysis of the Electrochemical Stability of Sulfide Solid Electrolyte Dry Films for Improved Dry‐Processed Solid‐State Batteries

Advanced Functional Materials, EarlyView.
An adapted processing for solvent‐free argyrodite solid electrolyte films based on insights into degradation mechanisms of the widely used binder polytetrafluoroethylene is presented. By adapting the dry film processing, long‐term cycling in Si||NMC pouch cells is demonstrated over more than 1000 cycles with a capacity retention of more than 80%, and ...

3D Digital Light Processing of Redox‐Active Polymers for Electrochemical Applications

Advanced Functional Materials, EarlyView.
3D printing of electrochemically switchable conducting polymers is achieved by Digital Light Processing of redox‐active carbazole‐based polymer materials. Complex 2D and 3D architectures including dot arrays and pyramids clearly show the potential for novel 3D switchable electrochemical devices for sensors, electrochromic displays as well as 3D printed

Deformation and Degradation in 18650 Li‐Ion Cells Under Freeze‐Thaw Cycling

Advanced Functional Materials, EarlyView.
This study investigates the impact of freezethaw degradation of 18650 cells via combined electrochemical and x‐ray imaging studies. High‐resolution synchrotron X‐ray tomography reveals deformation of the jelly‐roll structure and delamination of electrode active materials in cells cycled at 1C and 4C. These structural changes are quantitatively assessed
