Abstract
The present disclosure relates to a method for prelithiation, and in particular, to a method for prelithiation that predopes lithium into at least one unit cell uniformly in large amounts. According to an aspect of the present disclosure, there is provided a method for prelithiation including an 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 reaction tank, and connecting electrodes having the same polarity, adding an electrolyte solution into the reaction tank, disposing a lithium metal plate in the electrolyte solution, and connecting the lithium metal plate to the anode, and doping the anode.
