Methods for fast-charging batteries while minimizing lithium plating (LP) comprise charging the battery in a first phase at a near-maximum charging current, subsequently charging the battery in a second phase by decreasing the charging current while charging in order to maintain the anode potential equal to or above an anode potential threshold, and subsequently charging the battery in a third phase at constant cell potential such that the cathode potential remains below a cathode potential threshold. LP can be detected by determining the derivative of the charging current and examining the derivative for smooth curves or local discontinuities, wherein a smooth curve indicates the absence of LP and a curve with a local discontinuity indicates the presence of LP. A fast-charging profile can be defined by plotting the cell potential vs. the charging current from the first phase, the second phase, and the third phase to define a fast-charging profile.
