SAGGER FOR FIRING SECONDARY BATTERY ACTIVE MATERIAL AND METHOD FOR MANUFACTURING SECONDARY BATTERY ACTIVE MATERIAL USING SAME
The present invention relates to a sagger for firing an object to be fired including an active material for a secondary battery. The sagger comprises a notch portion that is recessed from an upper portion of a side wall thereof to open a portion of the side wall, wherein the ratio of the area of the notch portion to the area of the side wall is 30% to 70%, and an edge where a side wall of the sagger contacts a lower surface of the sagger is configured by a round portion. According to the present invention, 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.
