Abstract

A vertical-type firing apparatus for a positive electrode material for a secondary battery, for vertically moving and firing the positive electrode material for the secondary battery, comprises: a vertical-type firing furnace including an exhaust part, an air supply part, and a firing space positioned between the exhaust part and the air supply part; and a heater for heating the firing space of the vertical-type firing furnace, wherein the firing space includes a temperature-raising space, a cooling space, and a temperature-maintaining space located between the temperature-raising space and the cooling space, and the temperature of the temperature-maintaining space is higher than the temperature of the temperature-raising space and the temperature of the cooling space.
