Abstract

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.

Description

technical field [0001] The invention relates to a high-temperature reaction kettle, in particular to a high-pressure reaction kettle for manufacturing negative electrode materials of lithium ion batteries, which is used to realize the coating carbonization process of negative electrode materials of lithium ion batteries. Background technique [0002] Lithium-ion batteries are currently the most popular rechargeable batteries. An ideal lithium battery has the characteristics of long life, small size, light weight, high energy density, safety, environmental compatibility, and low cost. Existing lithium-ion batteries generally cannot fully have the above-mentioned advantages. The actual capacity and energy density provided by most batteries is much lower than their theoretical values. Under severe operating conditions, the actual performance of the battery is even worse, mainly due to the low utilization rate and serious polarization of the battery material. Therefore, resea...
