Article on "Analysis on Electrochemical Reaction of Lithium Titanium Oxide Li4Ti5O12" by Kazuhiko Mukai et al., was published in Energy Storage Materials.

Zero-strain insertion material, Li4Ti5O12, has garnered significant attention as an ideal electrode material for long cycle-life lithium-ion batteries, owing to its negligible volume change during the electrochemical reactions. However, this same characteristic hinders in-depth understanding of the reaction mechanism for more than 30 years, restricting widespread applications to electric and hybrid electric vehicles. We thus employed the recently developed operando X-ray absorption and X-ray diffraction techniques in Toyota beamline at the synchrotron radiation facility, SPring-8, and revealed detailed structural variations at the atomic and microscopic scale. The obtained results are useful for all-solid-state lithium-ion batteries, in which robust interfaces between electrodes and electrolyte are required.
