A kind of coating device and coating method of graphene lithium battery pole piece

Abstract

The invention discloses a graphene lithium battery pole piece coating device and a coating method thereof, comprising a coating device body, and a coating chamber, a drying chamber and a transfer chamber are arranged in the coating device body from top to bottom The upper side of the coating chamber is open and a top plate is fixedly connected to the opening, and a coating port is opened in the top plate, and a pair of guide rollers and a pair of guide rollers and A pair of coating rollers, the two coating rollers are connected with first motors, telescopic cylinders are installed on the sides of the two first motors away from each other, a coating cavity is opened in the top plate, and the coating The inner walls of the other two sides of the cloth mouth are connected with the paint cavity above the coating roller and have a paint outlet pipe, and the end of the paint outlet pipe away from the paint chamber is the lower end. The advantages are: the invention can freely control the coating thickness, improve the coating quality, and change the wind force according to the height during subsequent drying, so that the coating is more uniform.

Description

technical field [0001] The invention relates to the field of coating technology, in particular to a coating device and a coating method for a graphene lithium battery pole piece. Background technique [0002] Graphene lithium battery is a new energy battery developed by utilizing the characteristics of rapid and large-scale shuttle movement of lithium ions between the graphene surface and electrodes. The battery pole piece is the core component of the battery. When producing the battery pole piece, it needs to carry out the process of powder slurry, coating, rolling and shearing. Among them, coating is the key process of producing the battery pole piece. [0003] In the electrode production process, it is necessary to use a coating device to mix electrode materials and coat a fluid coating on the substrate, and then dry and shape it. The existing coating device has a simple structure and cannot control the coating thickness. Moreover, it cannot be quickly dried and set afte...

Problems solved by technology

[0003] In the electrode production process, it is necessary to use a coating device to mix electrode materials and coat a fluid coating on the substrate, and then dry and shape it. The existing coating device has a simple structure and cannot control the coating thickness. Moreover, it cannot be dried and set quickly after coating, and may fall due to the flow of the paint, resulting in uneven coating and low coating quality
