Spectroscopic Neutron Imaging of Lithium-ion Battery Electrolytes
Abstract: Lifetime and safety of high energy density storage devices such as lithium-ion batteries (LIBs) remain an important focus on the development of future devices. The formation of the solid electrolyte interphase (SEI) within LIBs during the initial few charges is critical for cell performance and cycle life. The SEI is a passivating film that forms on the electrodes of a LIB to avoid continuous reaction of the electrode with the electrolyte, it is therefore a critical component of safety and performance of these systems. Electrolyte composition plays a key role in how the SEI will be formed, the compounds chosen will determine LIB safety and longevity. Neutron imaging has the capability of studying electrolyte reactivity by observing gas generation, but with the use of an energy sensitive detector researchers can study electrolyte dynamics further. Spectroscopic neutron imaging (SNI) utilizes an energy sensitive detector and leverages hydrogen?s wavelength-dependent properties of hydrocarbon-based organic solvents within LIB electrolytes. This work aims to further development this technique with relevant electrolytes to enable a novel way to monitor real-time physical and chemical changes in electrolytes, exploring the roles of various compounds and reaction heterogeneity throughout LIB cells. This technique is vital in understanding the various roles the electrolyte compounds play in SEI formation and how researchers can develop the advanced electrolytes of the future.
