Lithium battery pole piece cleaning equipment and method

Abstract

The invention provides lithium battery pole piece cleaning equipment and method. The lithium battery pole piece cleaning equipment comprises a main control unit, a fixing device, a wetting device, a dust suction device and a cleaning device, wherein the fixing device, the wetting device, the dust suction device and the cleaning device are connected with the main control unit. The fixing device isused for fixing pole pieces. The wetting device is used for spraying a wetting agent to a cleaning area of each pole piece, so that cleaning is convenient to conduct, and abrasion of the pole pieces is reduced. The dust suction device is used for collecting coating particles generated after cleaning. According to the cleaning device, the powder brushing work is conducted on the pole pieces throughcleaning brushes. By means of the lithium battery pole piece cleaning equipment and method, a local coating can be cleaned rapidly, and pole lugs can be welded conveniently; meanwhile, the cleanliness and flatness of each cleaning area can be reported, the research and development cost of an enterprise can be remarkably lowered, and economic benefits of the enterprise are increased; market competitiveness of products is powerfully improved, and the equipment and method can be widely applied to production conveniently; and the great production practice significance is achieved.

Description

technical field [0001] The invention belongs to the technical field of lithium batteries, and in particular relates to a lithium battery pole piece cleaning device and a cleaning method. Background technique [0002] Due to its high energy density and good electrochemical performance, lithium-ion batteries have become energy transfer storage devices for these clean energy sources. In recent years, they have achieved a certain scale and market share with an astonishing development speed. In the development and production process of lithium-ion batteries, it is necessary to clean the pole pieces coated with positive and negative electrode coatings, so that they can be assembled into some test components to detect the electrochemical performance of materials or pole pieces. [0003] At present, there is no reliable method for cleaning the pole piece, which seriously hinders the evaluation progress of material performance or pole piece performance. The development of materials ...

Problems solved by technology

The cleanliness and flatness of this area will seriously affect the stability and contact resistance of the welding area, such as poor welding will seriously affect the internal resistance of the battery, thereby affecting the electrochemical performance of the battery

At present, blades are generally used to clean the coating area, the cleaning efficiency is low, and it is easy to cause wrinkles in the cleaned area and other phenomena that affect welding, which seriously restricts the assembly efficiency and manufacturing cost of special-shaped pole piece batteries.
