摘要： The present invention relates to a saggar for firing an active material of a secondary battery, a method for manufacturing the saggar, and a method for firing the active material. The saggar for firing an active material of a secondary battery according to the present invention has a coating layer formed on a bottom surface or a wall surface thereof so as to collect carbon dioxide. By means of the coating layer, the concentration of the carbon dioxide in the saggar can be lowered by collecting the carbon dioxide that is a by-product resulting from a firing reaction, thereby enabling a reduction in the amount of remaining lithium in the active material. The saggar of the present invention provides the saggar for firing an active material of a secondary battery, wherein the saggar has at least one through hole in the bottom surface, or the bottom surface and wall surfaces thereof so as to communicate a gas.
