ChemElectroChem, Volume 13, Issue 12, 17 June 2026.This study probes why polymer electrolyte membrane electrolyzers lose efficiency under different operating profiles. Using electrical tests, microscopy, and spectroscopy, Ti‐PTL passivation is established as the dominant cause for increased Ohmic resistance in samples aged under constant and triangular current profiles for 88 h.

Advanced Functional Materials, Volume 36, Issue 49, 18 June 2026.A Zn2+‐coordinated poly(vinylidene fluoride) binder is shown to suppress Jahn–Teller‐driven Mn dissolution while improving dispersion, wettability, and structural integrity in thick MnO2 cathodes. This simple binder‐engineering strategy enables high‐loading aqueous Zn‐ion batteries with enhanced areal capacity, cycling stability, and practical promise ...
