A sodium secondary battery module, according to an exemplary embodiment of the present invention, may comprise: unit stacks in which a plurality of unit cells are laminated, the plurality of unit cells each having an upper cap and a lower cap which seal up a plate-shaped solid electrolyte and a positive electrode component and a negative electrode component which are plate-shaped and respectively disposed on two sides of the solid electrolyte; separators which are interposed between the unit stacks while the plurality of unit stacks are arranged in columns and rows, so as to separate spaces between the unit stacks; and a case for accommodating the plurality of unit stacks and the separators.

A sagger for firing an object to be fired includes an active material for a secondary battery. Carbon dioxide that is a reaction by-product produced during a positive electrode active material firing process can be smoothly discharged from the sagger, and such a smooth discharge of carbon dioxide can lower a residual lithium concentration of a positive electrode active material and thus can improve dispersibility of a positive electrode active material slurry and also improve capacity of a battery.
