Description

Cross-reference to related applications: This disclosure claims priority to Chinese Patent Application No. 202410182135.8, title “High-efficiency reaction vessel,” filed on 18 February 2024, and all contents of said Chinese Patent Application are incorporated herein by reference. Technical field This disclosure relates to the technical field of the production of ternary precursors, and more particularly to a highly efficient reaction vessel. In the production process of ternary precursors, the synthesis process is the core process of the entire product production. In conventional techniques, when synthesizing ternary precursors, each raw material is generally added to the reaction vessel, and then stirred to ensure that each raw material reacts sufficiently, dispersing them in the slurry within the vessel in a timely manner. During the reaction, the slurry needs to be stirred by a stirring device in the reaction vessel. This creates a flow field within the vessel, which, ideally, mixes the raw materials. This flow field rapidly moves downwards in the center of the vessel, then moves to the edge of the vessel at the bottom, allowing the raw materials to react sufficiently. After reaching the edge, it moves relatively slowly upwards, and finally returns to the center of the vessel in the upper region, recirculating the slurry. However, the above reaction process is relatively slow and has relatively low productivity. In light of this, this disclosure provides a highly efficient reaction vessel. This reaction vessel can improve productivity and product quality.
