Claim:
1. A method for prelithiation, comprising: preparing at least one unit cell, the unit cell comprising a cathode, an anode, and a separator interposed between the cathode and the anode; disposing the prepared at least one unit cell in a first one of a plurality of sections of a reaction tank, and connecting electrodes having the same polarity, the sections being defined within the reaction tank by at least one support partition wall positioned inside the reaction tank to separate the sections; adding an electrolyte solution into the reaction tank; disposing a lithium metal plate in the electrolyte solution, and forming a direct electrical connection between the lithium metal plate and the anode without forming a direct electrical connection between the lithium metal plate and the cathode, the direct electrical connection being established by a conductor selected from the group consisting of a conducting line, a wire, and a cable; and doping the anode.
