Rapidly forming an electrode

A method for transforming a negative electrode for a lithium-ion cell, comprising the steps of, first constant-current charging with a first charging current until a first half cell potential against a reference electrode, the first constant-voltage charge in the first half-cell potential versus the reference electrode until a second charging current, second constant-current charging with the second charge current until a second half-cell potential vs. the reference electrode, the second constant voltage charging in the second half-cell potential versus the reference electrode until a final charging current.
