Description

technical field [0001] The invention belongs to the technical field of battery preparation, and in particular relates to a quantitative liquid injection device for large quantities of lithium batteries. Background technique [0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as the positive and negative electrode materials and uses non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream. The most important step in the process of lithium battery processing is the process of injecting lithium batteries. Due to the lithium hexafluorophosphate in the electrolyte, it is easy to react with water to produce hydrogen fluoride. Acid, so it needs to be injected in a vacuum or low humidity environment. Lithium battery injection vo...
