Control system for automatically adjusting viscosity of lithium battery slurry

Abstract

The invention discloses a control system for automatically adjusting the viscosity of lithium battery slurry. The control system comprises a vacuum planetary dispersion stirrer, a circulating pipeline A, a circulating pipeline B, a circulating pipeline C, a coating production device and a main control system, wherein the vacuum planetary dispersion stirrer is connected with the circulating pipeline A, the circulating pipeline A is connected with the circulating pipeline B, the circulating pipeline B is connected with the circulating pipeline C, and the circulating pipeline C is connected with the coating production device. The control system has the advantages that: the structure is simple, the design is reasonable, a novel lithium battery slurry preparation method is provided, and the control way for producing the lithium battery slurry is enlarged; the situation that the viscosity of the slurry is manually detected by using a laboratory is reduced, and the automatic detection and the automatic adjustment are realized; and the lagging phenomenon for adjusting the viscosity of the slurry during the slurry preparation of the lithium battery is reduced, and the viscosity is automatically and stably controlled during the slurry preparation process of the lithium battery, so that the device is more intelligent.

Description

technical field [0001] The invention relates to the field of battery manufacturing, in particular to an automatic adjustment of the viscosity of lithium battery slurry [0002] degree of control system. Background technique [0003] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the positive electrode material and uses a non-aqueous electrolyte solution. The earliest lithium battery came from the great inventor Edison, using the following reaction: Li+MnO 2 =LiMnO 2 The reaction is a redox reaction, discharge. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have become the mainstream now. [0004] During the manufacturing process of lithium-ion power batteries, viscosity is an important parameter that ne...
