Problems solved by technology

[0003] However, after the positive plate is soaked with acid, the layer of lead sulfate formed on the surface will be converted into relatively loose lead dioxide after formation and charging. Scattering into the air will pollute the workshop environment
And if the plate with too much floating powder is put into the battery, the floating powder will fall off and sink to the bottom of the battery, which will easily cause a short circuit inside the battery.

Embodiment 1

[0023] Please refer to figure 1 , in the present embodiment, a kind of plate treatment method comprises the steps:

[0024] Step a, carrying out plate-coating treatment on the pole plate;

[0025] In this step, the plate coating treatment can adopt the plate coating operation in the prior art.

[0026] Step b, using a water-absorbing material to absorb the moisture on the surface of the coated plate;

[0027] Specifically, this step may be: passing the plate-coated pole plate over a pressure roller, and winding the water-absorbing material on the pressure roller. The role of the water-absorbing material is to absorb the moisture on the surface of the plate, which has the following characteristics: 1. The material is soft, easy to wrap around the pressure roller, and will not crush the plate; 2. Does not contain iron, manganese, copper, chlorine Equally variable ionic components will not pollute the plate; 3. It has a good water absorption effect. For example, absorbent cot...

Embodiment 2

[0034] In this example, the pressure roller assembly used in step b of the electrode plate treatment method described in Embodiment 1 includes a pressure roller and a water-absorbing material wound on the pressure roller. The water-absorbing material is mainly used to absorb moisture on the surface of the electrode plate, which is convenient for subsequent drying treatment. The role of the water-absorbing material is to absorb the moisture on the surface of the plate, which has the following characteristics: 1. The material is soft, easy to wrap around the pressure roller, and will not crush the plate; 2. Does not contain iron, manganese, copper, chlorine Equally variable ionic components will not pollute the plate; 3. It has a good water absorption effect. For example, the water-absorbing material can be absorbent cotton yarn, etc., wherein the absorbent cotton yarn is usually replaced within a certain time of normal operation to ensure the drying of the absorbent cotton yarn...

Abstract

The invention relates to a polar plate treating method and a compression roller assembly used for the same. The polar plate treating method comprises the following steps of: step a, carrying out plate coating treatment on a polar plate; step b, absorbing water on the surface of the polar plate subjected to the plate coating treatment by utilizing a water-absorbing material to; and step c, carrying out drying treatment on the polar plate. According to the invention, after the plate is coated, the water-absorbing material is directly used for absorbing the water on the surface of the polar plate; and then, the polar plate is dried. The whole treating process can save acid pouring operation, so that not only can acid liquid be saved, but also the problem in the prior art that floating powder is easy to generate due to acid pouring is avoided. Furthermore, the moisture content of the polar plate machined by the method disclosed by the invention meets requirements.

Description

technical field [0001] The invention relates to a method for drying polar plate coating and a pressure roller assembly used in the method. Background technique [0002] In the existing battery manufacturing process, the pole plate is subjected to acid leaching treatment between the plate coating process and the drying process. The purpose of the acid leaching treatment is to prevent the plate from sticking when the plate is collected. Among them, the principle of acid leaching treatment is to pour acid solution onto the plate after coating. During the acid leaching process, a layer of lead sulfate will be formed on the surface of the plate. This layer of lead sulfate can be used to reduce the gap between the plates. bonding between. [0003] However, after the positive plate is soaked with acid, the layer of lead sulfate formed on the surface will be converted into relatively loose lead dioxide after formation and charging. Scattering into the air will pollute the workshop...
