Embodiment Construction

[0023] Such as Figure 1-5 As shown, a lithium battery pole piece processing method, the steps of the processing method can be divided into:

[0024] a. Slurry preparation: prepare slurry through slurry mixing equipment;

[0025] b. Slurry coating;

[0026] c. Pole sheet rolling;

[0027] d. Pole piece cutting;

[0028] e. The pole pieces are dried.

[0029] The slurry coating is to uniformly coat the prepared slurry on the pole piece to form a coating.

[0030] The pole piece rolling refers to placing the coated pole piece between the moving roller and the static roller, and pushing the pole piece backward while the slurry is pressed into the pole piece through the rotation of the moving roller.

[0031] The pole piece drying means that the pole piece to be dried is baked in an infrared baking room, and then baked in a blast baking room.

[0032] The lithium battery slurry mixing equipment includes a cylinder body 1, a cylinder body space arranged in the cylinder body 1...

Abstract

The invention discloses a lithium battery pole piece processing method. The steps of the processing method can be divided into: slurry preparation; slurry coating; pole piece rolling; pole piece cutting; pole piece drying. The method is simple to implement, During slurry preparation, the working efficiency can be improved by speeding up the mixing speed of water and slurry.

Description

technical field [0001] The invention belongs to the field of lithium battery processing, in particular to a method for processing lithium battery pole pieces. Background technique [0002] Lithium batteries have the advantages of small size, high energy, and no pollution, and have been more and more widely used in portable electronic products such as mobile phones, digital cameras, and notebook computers. However, in the traditional lithium battery processing method, when slurry preparation Mixing the slurry with water is too slow, reducing work efficiency. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a lithium battery slurry mixing device capable of improving work efficiency by increasing the mixing speed of the slurry and water. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a lithium battery pole piece processing method, the steps...
