Improving the oxygen evolution reaction activity of Co-based oxides by phosphate functionalization
Our findings disclose that P-functionalization successfully enhances the oxygen evolution reaction (OER) activity of different cobalt-based catalysts (namely, La0.2Sr0.8CoO3–δ, La0.2Sr0.8Co0.8Fe0.2O3–δ, and CoOx) at near-neutral pHs and that both phosphate ion assistance in the OER mechanism and catalyst Co oxidation state can play a role in the enhanced OER activity.

Observing solid-state batteries during deformation
PSI researchers have observed mechanical processes in solid-state batteries with unprecedented precision. Using X-ray tomography at the Swiss Light Source SLS, they discovered how fissures inside the batteries propagate. These insights can help to make batteries for electric cars or smartphones safer and more efficient.
