Abstract
Fast-charge protocols that prevent lithium plating are needed to extend the life span of lithium-ion batteries. Here, we describe a simple experimental method to estimate the minimum charging time below which it is simply impossible to avoid plating at a given temperature. We demonstrate that, by gauging and correcting the ohmic drop that is intrinsic to reference electrodes, the local potential at the anode surface can be reasonably approximated. This finer anode control enables the determination of the maximum average rate at which lithium deposition can be mitigated, establishing realistic boundaries that can inform the development of advanced charging protocols.
