1. A chemically or electrochemically pre-lithiated cathode for use in an electrochemical cell comprising:
a pre-lithiated cathode active material wherein the cathode active material comprises the chemical formula: Li1+aMxOy where
0<a≤1,
0<x,
2≤y≤6, and
M is one or more elements selected from the group consisting of one or more transition metals, Al, B, Mg, and combinations thereof, and
wherein the pre-lithiated cathode active material has a thermodynamic potential less than 3.0 V versus Li prior to assembly into an electrochemical cell; and
wherein a thermodynamic potential of the pre-lithiated cathode is less than 2.5 V versus Li.
