Abstract

The invention discloses a positive electrode homogenizing device for lithium battery processing. The device comprises a device body, a first liquid conveying pump, a glue making tank and a second liquid conveying pump, a material conveying pipe and a first motor are arranged at the upper end of the device body, the material conveying pipe is arranged on the left rear side of the first motor, and the second motor is connected with a second rotating shaft; the lower end of the second rotating shaft penetrates through the upper end of the glue making tank and is connected with a second transmission shaft, the second transmission shaft is rotatably connected to the inner top end of the glue making tank, the second liquid conveying pump is arranged at the lower end of the glue making tank, theend, away from the second liquid conveying pump, of a second connecting pipe is communicated with the upper end of a liquid storage tank, and a third liquid conveying pump is connected with a third connecting pipe. According to the positive electrode homogenizing device for lithium battery processing, a proper amount of a binder in a binder tank is added into the glue making tank, a proper amountof a solvent is added through a solvent feeding port, and the solvent and the binder are premixed and stirred through the second transmission shaft and a second stirring blade under the action of thesecond motor, so that subsequent mixing processing is facilitated.

Description

technical field [0001] The invention relates to the technical field related to lithium battery processing, in particular to a positive electrode homogenizer for lithium battery processing. Background technique [0002] Lithium-ion batteries, also known as rechargeable batteries, mainly rely on the movement of lithium ions between the positive and negative electrodes to work. The manufacturing process of lithium-ion batteries includes two steps of homogenization and coating. Cloth and the performance of the final finished battery play a decisive role. Lithium battery cathode homogenate is composed of raw materials such as lithium cobaltate, conductive agent, binder and solvent. However, the existing cathode homogenizer for lithium battery processing will The mixed raw materials are added to the mixing tank for stirring and processing, which may easily cause uneven stirring between the raw materials, and the corresponding raw materials cannot be pre-mixed and stirred before th...
