Abstract: The present disclosure relates to a method for manufacturing a coin-type secondary battery. The method includes at least: bonding one or more solid electrolytes to an anode upper case; forming an anode active material layer on an anode current collector; sequentially stacking the anode current collector on which the anode active material layer is formed and the anode upper case to which the one or more solid electrolytes are bonded on an anode bottom case to obtain an anode part; sequentially stacking the anode part, a separator, a cathode current collector, and a second case including one or more openings on a first case; bonding the first case to the second case; and introducing an ion-containing solution containing sodium, lithium, magnesium, and a combination thereof from the outside of the second case into an interior thereof.
