An electrode slurry stirring device for lithium ion battery production

Abstract

The invention discloses an electrode slurry stirring device for lithium-ion battery production, which comprises a base plate, a mounting rod is fixed vertically on the upper surface of the base plate, a connecting rod is arranged on the side of the mounting rod, and a connecting rod is installed on the connecting rod. A snake coil tube, a transmission flexible shaft is plugged inside the snake coil tube, a rotating motor is fixedly installed on the upper end of the transmission flexible shaft, and a plurality of dispersers and agitators are set on the driven flexible shaft. The beneficial effect is that the electrode slurry stirring device for lithium-ion battery production according to the present invention can realize continuous material feeding and discharging without stopping the machine, without delaying production time, effectively improving production efficiency, and is suitable for large-scale production of lithium-ion batteries.

Description

technical field [0001] The invention relates to the field of lithium ion battery production, in particular to an electrode slurry stirring device for lithium ion battery production. Background technique [0002] Lithium-ion battery is a secondary battery (rechargeable battery) that mainly relies on the movement of lithium ions between the positive and negative electrodes to work. During the charging and discharging process, Li+ intercalates and deintercalates back and forth between the two electrodes: when charging, Li+ is deintercalated from the positive electrode, intercalated into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge. [0003] The production process of lithium batteries is relatively complicated. The main production process covers the stirring and coating stage (front stage) of electrode production, the winding liquid injection stage (middle stage) of cell synthesis, an...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide an electrode slurry stirring device for lithium-ion battery production in order to solve the above problems, so as to solve the problem that the traditional lithium-ion battery production mixer in the prior art cannot realize continuous feeding and discharging, and needs to be shut down during the stirring process. Unloading and feeding delays production time, resulting in long-term stirring production efficiency at a low level, which is not suitable for large-scale production and use of lithium-ion batteries.
