64220 2025 eng lecture 0 -- -- -- Interfaces Under the Isotopic Lens: Rethinking Degradation in Lithium-Ion Batteries This work investigates Li isotope fractionation in Li-ion batteries, questioning whether there is a correlation between chenges in isotopic distribution and battery capacity loss (cell degradation). The results point to Li-isotope distribution as a new benchmark for electrode/electrolyte interfaces investigation, which can potentialy provide information about the interface formation mechanism.
