Abstract: The present disclosure provides a negative electrode for an electrochemical cell that cycles lithium ions. The negative electrode may include a negative electroactive material and a lithiation additive. The negative electroactive material may have a first cell voltage window. The lithiation additive may have a second cell voltage window. The second cell voltage window may be less than the first cell voltage window. When the electrochemical cell is operated in the second cell voltage window, the lithiation additive may lithiated the cell.
