Effects of Carbon Nanoparticles on Triboelectro‐Induced Surface Defects

Advanced Engineering Materials, Volume 28, Issue 6, 18 March 2026.
Carbon nanoparticles added to grease modify the electrocontact behavior. The synergy of particle concentration and electric current dominates the surface damage of metals in contact. Electrical surface damage caused by current leakage is a critical challenge in high‐performance applications such as electric vehicle (EV) drivetrains and wind turbine ...

Design of Catalyst/Polyelectrolyte Interfaces for Anion Exchange Membrane Water Electrolysis Under Low‐Concentration Alkaline Conditions

ChemElectroChem, Volume 13, Issue 6, 17 March 2026.
Anion exchange membrane water electrolysis with a self‐supported Ni‐foam anode is used to dissect how catalyst–ionomer and membrane–catalyst layer interfaces govern performance under dilute alkaline conditions. Solvent‐controlled ionomer morphology and a Ni nanoparticle interlayer are shown to decrease cell resistance and OH‐ transport limitations ...

Tailored Redox‐Active Catholytes Enabling High‐Rate and High‐Loading All‐Solid‐State Lithium‐Sulfur Batteries

Advanced Materials, Volume 38, Issue 15, 12 March 2026.
This study explores iodine substitution in solid electrolytes to overcome sluggish redox kinetics and poor charge transport in all‐solid‐state Li‐S batteries. The resulting iodine‐rich, amorphous phase and superionic, nanocrystalline domains enable effective redox mediation and provide a robust ionic percolation network.

Engineering a Stable Solid–Electrolyte Interphase through a Novel Trifluoromethyl‐Free Lithium Salt for Lithium Metal Polymer Batteries

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 2, March 2026.
The motivation behind the development of the new lithium salt LiDFFSI is to combine the advantages of both LiFSI and LiDFSI salts. LiDFFSI offers high ionic conductivity and enhanced compatibility with aluminum current collectors. Additionally, it promotes the formation of a conductive SEI layer rich in LiF and LiH, which contributes to an extended ...
