Embodiment 1

[0036] In this embodiment, a coating mechanism 2 is provided, please refer to figure 1 , figure 1 This is a structural diagram of the slit coating device in the embodiment of this application, such as figure 1 As shown, the coating mechanism 2 includes: a base 200, a pallet 201, a movable support member 202, and a fluid storage tank 240 with a nozzle 210; the pallet 201 and the movable support member 202 are both fixed in the The base 200; wherein, the fluid storage tank 240 is fixed on the movable support member 202 to move relative to the pallet 201 under the drive of the movable support member 202; wherein, in the During the movement of the fluid storage tank 240, the fluid material in the fluid storage tank 240 is applied to the sample to be coated fixed on the pallet 201 through the nozzle 210 to form a film directly.

[0037] Specifically, the sample may be one or more of a positive pole piece or a negative pole piece.

[0038] In the specific implementation process, the slit...

Embodiment 2

[0057] In this embodiment, a slit coating device is provided, such as figure 1 As shown, the device includes:

[0058] Horizontal support platform 1; the horizontal support platform 1 is fixed with the coating mechanism 2, the base material transfer mechanism 3, and the film forming thermostat 4 provided in the first embodiment;

[0059] Wherein, the base material transfer mechanism 3 is located between the coating mechanism 2 and the film-forming incubator 4 to transfer the coated sample to the film-forming incubator 4 for heating to form a film.

[0060] Since the coating mechanism 2 has been introduced in detail in the first embodiment, it will not be repeated here.

[0061] First, the base material transfer mechanism 3 is introduced.

[0062] The main function of the base material transfer mechanism 3 is to realize the clamping, transfer and upside down of samples.

[0063] In the embodiments of this application, such as figure 1 with image 3 As shown, the base material transfer mec...

Embodiment 3

[0081] In this embodiment, a film preparation method is provided, please refer to Figure 5 , Figure 5 This is a step diagram of a film preparation method in an embodiment of this application. The method is applied to the slit coating device described in Embodiment 2. The method includes:

[0082] In step S501, the fluid storage tank 240 is moved relative to the pallet 201 under the drive of the movable support member 202, and the fluid material is uniformly applied to the pallet 201 through the nozzle 210 and fixed On the sample to be coated;

[0083] Step S502, the base material transfer mechanism 3 transfers the coated sample to the film forming thermostat 4;

[0084] In step S503, the coated sample is heated by the film forming thermostat 4 to form a film on the surface of the sample.

[0085] The following is an example of film formation on both sides of the sample to illustrate the method:

[0086] First, the fluid storage tank 240 is moved under the drive of the movable support...

Abstract

The invention discloses a coating mechanism, a slit coating device and a film preparation method. The coating mechanism comprises a base, a supporting table, a movable supporting part and a fluid storage tank with a nozzle, wherein both the supporting table and the movable supporting part are fixed on the base; the fluid storage tank is fixed on the movable supporting part and driven by the movable supporting part to move relative to the supporting table; and when the fluid storage tank moves, a fluid material in the fluid storage tank is sprayed by the nozzle onto a to-be-coated sample fixed on the supporting table for direct film formation. By adoption of the coating mechanism, the slit coating device and the film preparation method provided by the invention, the technical problems that a conventional gel polymer lithium battery film formation device and method are high in cost and low in film formation quality can be solved. Furthermore, the slit coating device provided by the invention is low in cost and uniform in coating effect.

Description

Technical field [0001] The invention relates to the technical field of battery manufacturing equipment, in particular to a coating mechanism, a slit coating device and a film preparation method. Background technique [0002] Lithium-ion batteries have been widely used in mobile phones, notebook computers and other electronic products because of their high working voltage, long cycle life, high energy density, small size, light weight, and low pollution, and become the power battery for electric vehicles in the future. One of the preferred power supplies. The gel polymer electrolyte has the dual functions of a separator and an ion-conducting carrier in the liquid electrolyte battery system. Since there is no or a small amount of free solvent in the system, gel polymer electrolyte can fundamentally solve the problems of liquid leakage, flammability and explosion that may occur during the use of traditional lithium ion batteries, and significantly improve the performance of lithium...
