The invention discloses a high-temperature reaction kettle for manufacturing a
lithium ion battery
cathode material. The high-temperature reaction kettle comprises a reaction kettle body, a spindle, a
solid charging port, a liquid inlet, a
nitrogen inlet, a gas outlet, a support and a discharging port. The high-temperature reaction kettle further comprises a rotary horizontal partition column, double parallel
helical tapes, a frame type guide scraping edge, a screw propulsion
system and a sealing head scraping wall
system. A stirring
system of the reaction kettle adopts the double parallel
helical tapes in cooperation with the frame type guide scraping edge and the rotary horizontal partition column in the middle for the first time, dead-corner-free material mixing is creatively achieved, and the mixing efficiency reaches the best state of all existing like devices. The problems of material production, stirring effect, reaction environment, discharging mode and the like required in the coated
carbonation process of a high-end
lithium ion battery
cathode material are solved by adopting the reaction kettle, and a mature manufacturing process is formed, so that the cycle life,
processing performance, surface stability,
discharge capacity, efficiency and the like of the
cathode material are comprehensively improved.
