ChemElectroChem, Volume 13, Issue 7, 1 April 2026.Accurate determination of the lithium‐ion diffusion coefficient requires a consistent definition of active surface area. Applying galvanostatic intermittent titration technique and intermittent current interruption to a commercial graphite electrode, we quantify how three common approximations—geometrical area (AGA), scanning electron microscopy ...

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 ...
