Laser Processing Facilitates Battery Production Manufacturing

Solution for Laser Surface Etching of Battery Electrode Sheets

Split line

With the increasing requirements for industrial manufacturing automation and intelligence in China, laser processing control technology has been continuously innovating and upgrading, laser processing is excellent processing characteristics have been widely applied across various fields. 

In the production and manufacturing process of batteries, laser processing technology is being used in more and more stages, Laser has become a highly effective technology for reducing costs and increasing efficiency in battery production.

In order to improve battery performance, In the production and manufacturing process of battery electrode sheets, Production process of laser etching using laser marking technology on the coating layer of battery electrode sheets. This process uniformly etches the coating on both sides of the electrode sheets, forming evenly deep etched lines on the coating layer of the electrode sheet. 

Laser processing is a non-contact processing method that does not cause mechanical deformation to the battery electrode sheets, Its flexible laser process parameter adjustments can meet different etching depth and length requirements. Laser processing is highly efficient and can match the coil-to-coil mechanism's material speed,enabling in-flight etching processing.
