Using a Zero‐Strain Reference Electrode to Distinguish Anode and Cathode Volume Changes in a Solid‐State Battery

Advanced Materials Interfaces, EarlyView.
Volume changes of a solid‐state battery cell are separated into the individual contributions of anode and cathode. Simultaneously determining the “reaction volumes” of both electrodes requires a reference electrode with a pressure‐independent potential.

Enhanced mechanical, thermotolerance, and anti-yellowing performance of glass fibre filled polyether-ether-ketone composites with enclosed polyether-ether-ketone polyamide acid sizing agent

Materials & Design
The application potential of glass fiber reinforced polyether-ether-ketone (GF/PEEK) composites is hampered by weak interfacial adhesion. This problem originates from the low wettability and the thermal decomposition of the interlayer at high ...

Optofluidic Raman Analysis and Capacity Recovery in Li‐ion Cells

Advanced Materials Technologies, EarlyView.
Operando Raman spectroscopy is used to monitor the degradation of commercial Li‐ion cells. Using a microfluidic access port, small amounts of electrolyte are sampled into a hollow‐core optical fibre, where fibre‐enhanced Raman analysis reveals Li+ solvation changes and solvent evolution.
