Abstract: A method for extending battery cycle life of Li-ion battery includes executing a fast formation protocol on a Li-ion battery cell (cell) such that an induced Li loss shifts an electrode-specific utilization range with a lithiation level of the positive electrode decreased to be less than or equal 94% as determined via differential voltage analysis. Also, the fast formation protocol of the cell includes charging the cell to a maximum charging voltage of the cell in less than 2 hours during a first formation cycle and avoiding a kinetically limited region of the positive electrode.
