Quantifying Heterogeneous Degradation Pathways and Deformation Fields in Solid‐State Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Mechanical, (electro)chemical degradation pathways in all solid‐state batteries and associated deformation fields around them are quantified using an in situ, multimodal strategy. The effects of electrolyte processing, cell assembly, and cycling are isolated. At the electrode interface and the terminal crack, stress is an order of magnitude higher than

Combined In Situ X‐Ray Spectroscopic and Theoretical Study on Trimetal Synergistic Enhancement of Water Oxidation

open access: yesAdvanced Energy Materials, EarlyView.
Trimetal synergistic enhancement of OER activity is observed in CaCu3Co2Ru2O12 catalyst, which exhibits a low overpotential of 198 mV at 10 mA cm‒2. In situ X‐ray absorption spectra reveal that the Co and Ru ions are active sites. Although Cu is not the active sites, it optimizes the electronic structure at the EF, leading to a synergistic enhancement ...
