Beneficial <i>vs.</i> inhibiting passivation by the native lithium solid electrolyte interphase revealed by electrochemical Li <sup>+</sup> exchange
Gustavo M. Hobold, Kyeong‐Ho Kim, Betar M. Gallant
Abstract
Electrolytes that achieve highest Li Coulombic efficiency display quantifiably higher rates of electrochemical Li + exchange. The effect is attributed to their improved SEI and better-percolated Li deposits that boost Li + exchange as the cell cycles.
