Research question
Why can lithium titanate charge rapidly when both its initial and fully lithiated phases conduct lithium ions poorly?
Key result
Metastable intermediate structures create low-barrier lithium-migration pathways at phase boundaries. Operando spectroscopy and calculations connected these transient local structures with fast charging.
Research contribution
Dong-Hwa Seo was an equal-contributing author on this collaborative study combining operando measurements and atomistic calculations. This paper includes work from his earlier affiliations.
