Description

Technical Field

[0001] The invention relates to the technical field of electrolyte production, in particular to a batching device for lithium ion battery electrolyte. Background Art

[0002] At present, in the production process of lithium-ion batteries, the uniformity of electrolyte batching directly affects the performance, safety and cycle life of the battery. Traditional electrolyte batching devices mostly use a simple stirring structure to mix the electrolyte through a stirring paddle rotating in a straight line or fixed trajectory. There are two main problems with this stirring method: on the one hand, due to the single motion trajectory of the stirring mechanism, different components are prone to sedimentation, retention or uneven distribution in the stirring chamber, reducing the mixing efficiency; on the other hand, in the process of raw materials entering the stirring chamber through the feed port, if there is a lack of effective buffering and preliminary mixing structure, impact flow is easily formed, which is not only not conducive to mixing uniformity, but may also cause impact loss to the stirring mechanism at the bottom, affecting the life of the device.

[0003] In addition, existing stirring power systems are mostly based on rotary motors or linear reciprocating structures, which fail to achieve complex, irregular trajectory motion. Therefore, the fluid disturbance during the stirring process is weak and cannot meet the preparation requirements of high uniformity and high stability electrolytes. At the same time, although some devices have introduced auxiliary stirring or multi-point feeding structures, due to the complex transmission path and poor synchronization of the structure, it is easy to cause low power transmission efficiency and even structural interference, further affecting the stability of the device and the mixing effect. Therefore, how to design an electrolyte batching device with a compact structure, rich motion trajectory and high stirring efficiency has become a key technical problem that needs to be solved in this field.
