A kind of electrode material mixing device for lithium ion battery production

Abstract

The invention discloses an electrode material mixing device for lithium-ion battery production, which comprises a frame, a battery and a crushing motor are arranged inside the frame, an organic case is fixedly installed on the upper end of the frame, and an outlet The material port, the upper end of the chassis is provided with a box cover. The beneficial effect is that: the electrode material mixing device for lithium ion battery production according to the present invention squeezes and pulverizes the agglomerated material through the mutual extrusion and sliding of the two extrusion plates, compared with the traditional one that uses a pair of extrusion The extrusion method of pressing rollers has high extrusion efficiency, complete extrusion, and good extrusion effect, so there is no need for secondary extrusion by screening, and the production speed is fast, the production efficiency is high, and the practicability is good.

Description

technical field [0001] The invention relates to the field of lithium ion battery production, in particular to an electrode material mixing 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

[0007] The purpose of the present invention is to provide a lithium-ion battery production electrode material mixing device in order to solve the above problems, so as to solve the problem that the traditional battery electrode material mixing equipment in the prior art cannot squeeze the material thoroughly and completely at one time, and must go through two Extrusion can only be completed once or even repeatedly, which is time-consuming and labor-intensive, and the production cost is high.
