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 activematerial 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.
本发明涉及一种用于对包含二次电池用活性材料的被烧制物体进行烧制的匣钵。该匣钵包括从其侧壁的上部凹进以使该侧壁的一部分敞开的凹口部分，其中该凹口部分的面积与该侧壁的面积的比率为30％至70％，并且匣钵的侧壁与匣钵的下表面接触处的边缘由圆化部分构成。根据本发明，作为正极活性材料烧制过程期间所产生的反应副产物的二氧化碳可以从匣钵顺畅地排出，并且二氧化碳的这种顺畅排出可以降低正极活性材料的残留锂浓度，并且因此可以提高正极活性材料浆料的分散性且还提高电池的容量。
