Abstract

An electrochemical cell is provided herein as well as methods for preparing electrochemical cells. The electrochemical cell includes a negative electrode and a positive electrode. The negative electrode includes a prelithiated electroactive material including a lithium silicide. Lithium is present in the prelithiated electroactive material in an amount corresponding to greater than or equal to about 10% of a state of charge of the negative electrode. The electrochemical cell has a negative electrode capacity to positive electrode capacity for lithium (N/P) ratio of greater than or equal to about 1, and the electrochemical cell is capable of operating at an operating voltage of less than or equal to about 5 volts.
