1. A method for lithiation of an electrode for use in an energy storage device, the method comprising:
providing a cell assembly including a negative electrode, at least one separator, and a positive electrode, the negative electrode or the positive electrode being an electrode to be lithiated, the cell assembly being disposed in and electrically connected to a cell packaging case;
providing a piece of lithium metal with predetermined weight;
electrically connecting the piece of lithium metal to an inner wall of the cell packaging case; and,
after said electrically connecting the piece of lithium metal to the inner wall of the cell packaging case, and with the cell assembly being disposed in and electrically connected to the cell packaging case, filling the cell packaging case with an electrolyte containing a lithium salt.
