Batteries: Imaging degradation [PDF]
Nature Energy, 2016 The degradation and failure of Li-ion batteries is strongly associated with electrode microstructure change upon (de)lithiation. Now, an operando X-ray tomography approach is shown to correlate changes in the microstructure of electrodes to cell performance, and thereby predict degradation pathways.

Diagnosing Battery Degradation via Gas Analysis [PDF]
ENERGY & ENVIRONMENTAL MATERIALS, 2022 Interfacial reactions in lithium‐ion batteries often involve gaseous reaction products. Mechanistic investigation of material degradation processes requires a technique to identify and quantify these gases in battery cells. On‐line electrochemical mass spectrometry (OEMS) is an operando gas analysis method that continuously samples the headspace of a ...
