[Surface Treatment Case] Surface treatment that streamlines the manufacturing process of lithium-ion batteries.

Prevention of adhesion of adhesive tape used in lithium-ion battery manufacturing. Achieving both extended maintenance periods and prevention of line stoppages with surface treatment suitable for cutting tools.

We would like to introduce a case study on the improvement of cutting equipment for insulation tape used in the manufacturing of lithium-ion batteries. ■ Key Issues - Problems arose when adhesive material adhered to the cutting blade, causing the line to stop. - The blade type is a shear type with two blades, similar to scissors. - To prevent line stoppages, frequent cleaning was required, which decreased production efficiency. ■ Selection Process - We wanted to perform surface treatment using commercially available blades. - It was necessary to select a surface treatment that does not change the cutting performance. - A long-lasting surface treatment was needed to prevent line stoppages and reduce cleaning frequency. ■ Effects of Coating - It was possible to strip the original surface treatment of commercially available blades for processing. - Adhesive adhesion was eliminated, reducing the labor required for cleaning. - Preventing line stoppages and the need for line stoppages for cleaning became unnecessary. Non-stick coating on blades contributes to improved productivity, cost reduction, and enhanced safety. We also have a collection of case studies and trial sets for improvements in the cutting process. ▽ Click here to apply for the collection of cutting process improvement case studies and trial sets ▽

Applications/Examples of results

【Other Cases】 Process of continuously cutting multilayer films ■Problem There is a layer of adhesive on the first layer of the film, causing adhesive to adhere to the rotary blade. This adhesion leads to cutting defects and line stoppages. ■Challenge To create a blade that can continuously cut without adhesive adhering to the rotary blade, a coating that prevents adhesion with excellent release properties and durability was required. Initially, a Bi-Coat® with superior durability and release properties was selected. The film thickness was about 10μm, and there was no visible change to the blade, but when actually cutting, the sharpness deteriorated to a point where it became unusable. Next, a silicone-based coating that would have little effect on the blade edge shape was proposed, but due to the high adhesive strength of the adhesive layer in the multilayer film, while cutting was possible, adhesion problems occurred. ■Adoption Process and Effects The rotary blade presses the edge against the film and cuts with pressure, resulting in minimal friction with the product. Therefore, MRS-004, which has excellent release properties and tackiness despite being a thin film, was proposed. As a result of testing, it was possible to maintain cutting performance without changes in the blade edge shape while continuously resolving the problems.
