Abstract
Understanding the fundamental properties of electrode-electrolyte interphases (EEIs) is essential for designing electrolytes that support stable operation under high charging rates. In this study, we benchmark our fast-charging electrolyte (FCE) against the commercial LP57 electrolyte to identify the EEI characteristics that enhance fast-charging performance. By utilizing the latest advances in time-of-flight secondary ion mass spectrometry (TOF-SIMS) and focused-ion beam (FIB) techniques, we reveal the complex chemical architecture of the cathode-electrolyte interphase (CEI). Our findings indicate that stable battery operation under fast-charging conditions requires reduced surface reactivity rather than…
