Spectroscopic Neutron Imaging to Resolve Electrolyte Degradation in Operando Fast-Charging Li-Ion Batteries

Abstract: In this experiment, we will further develop time-of-flight neutron imaging (ToF-NI) as a spectroscopic method to investigate the physical and chemical state of the electrolyte in Li-ion batteries (LIBs) after failure due to fast-charging protocols and under the influence of external temperature variations. This will allow: 1) to track the effects of temperature gradients in LIB electrolytes without invasive probes, 2) to correlate the effects of fast charging (up to 5C) to electrochemical performance, electrolyte health, and cycle life in LIBs, and 3) to correlate the variations of 1H neutron cross-sections (1HCS) to chemical changes due to degradation processes in the electrolytes. This experiment is a follow up of our latest findings, where we use ToF-NI to differentiate between CHn bonds in liquid organic molecules by calculating their 1HCS.
