Description

technical field [0001] The invention relates to the technical field of battery processing, in particular to an integrated system for processing lithium-ion battery slurry with spiral circulation stirring. Background technique [0002] As the environment continues to become severe, human survival is in great danger, especially the rising global temperature, which has sounded the alarm for all human beings. Carbon dioxide and other harmful gases are increasing, so using clean new energy instead of fossil energy to reduce carbon dioxide and other harmful gases is the only way for the development of all mankind. Lithium-ion batteries have the characteristics of high energy density, small self-discharge, no memory effect, wide operating voltage range, long life, and no environmental pollution. They are currently the best choice for power vehicles to replace fossil energy, and they are also a hot spot in the development and research of the automotive industry. and directions. ...

AI Technical Summary

Problems solved by technology

[0003] The capacity, quality and life of lithium-ion batteries are the three eternal themes pursued by the development of lithium-ion batteries. At present, the quality of lithium-ion batteries is unstable, their safety performance is poor, and their lifespan is short, which hinders the use of lithium-ion batteries in the automotive industry. However, the manufacturing process of lithium-ion batteries is a key factor affecting the quality, life and safety of lithium-ion batteries. Each link will have a profound impact, so how to prepare high-quality slurry is currently a research hotspot in the lithium battery industry

[0004] The manufacturing process of lithium-ion batteries is complicated and there are many influencing factors. At present, most lithium battery manufacturing enterprises have not realized automatic processing of the entire slurry preparation process, and the process is relatively discrete. The slurry is easily affected by impurities, dust, and moisture in the environment during the stirring process. , and eventually the impurities and dust in the air will be brought into the pole piece, which will lead to a safety accident of the lithium-ion battery in severe cases; there is a dead angle in the stirring process, so that the slurry in some parts of the mixer cannot be fully stirred, and some of them are larger. Due to the limitations of the stirring method and stirring intensity of the mixer, the slurry cannot be fully stirred, dispersed and uniform; in each process of lithium-ion battery slurry preparation, the influence of the environment and various process parameters is not fully considered. Interaction between process parameters, etc.
