Web Control Products for Lithium Battery Industry
Arise has over two decades of expertise in web control, with solutions covering the core processes of lithium battery electrode manufacturing — coating, calendering, slitting, and winding. Arise web control products are widely used in the production of positive and negative electrodes, ensuring web path stability, coating accuracy, and dimensional consistency at high speeds, with seamless integration into existing production lines.
Lithium battery electrode manufacturing demands exceptional precision and stability. Coating alignment accuracy and margin width tolerances directly determine cell electrochemical performance and safety; slitting width accuracy and burr control affect subsequent winding alignment and battery short-circuit risk. Any wandering, tension fluctuation, or dimensional deviation can trigger large-scale rejects. Arise’s web guiding, tension control, online width measurement, and inspection systems effectively reduce waste, stabilize quality, and lower labor costs, helping lithium battery manufacturers maintain product consistency and safety in high-speed continuous production.
Web Control Solutions for Lithium Battery Industry
Coating is a critical process in lithium battery electrode manufacturing, where precise control of electrode margin width and front-to-back coating alignment is essential for ensuring cell performance, consistency, and safety. Any deviation in coating position or edge alignment can affect electrode quality and may lead to material waste, reduced production efficiency, or batch rejection.
During high-speed coating operations, substrate wandering can cause misalignment between the front and back coatings, resulting in dimensional inconsistencies and defective electrodes. Arise’s Web Guide System provides continuous and precise substrate centering throughout the coating process, ensuring stable material positioning. The CK-2000A online vision width measurement system monitors coating margin widths and edge alignment deviations in real time, with inspection data transmitted to the line control system for closed-loop correction. These solutions help battery manufacturers improve coating accuracy, reduce defects, and achieve stable, high-quality electrode production.
Calendering is an essential process in lithium battery electrode manufacturing, where dried electrode coatings are compacted to achieve the required density, thickness, and structural consistency. During this process, fluctuations in material tension can cause electrode stretching, wrinkling, coating cracks, or deformation, which may negatively impact battery performance and production yield.
Arise’s Tension Control System creates a closed-loop constant tension control process between the calender entry and exit sections, maintaining stable electrode movement throughout compaction. By minimizing tension variations, the system helps prevent electrode deformation and coating damage, ensuring consistent thickness, improved process stability, and higher-quality electrode production.
Slitting is a key process in lithium battery electrode manufacturing, where wide electrode webs are precisely divided into multiple narrow strips for subsequent cell assembly processes. Slitting accuracy directly affects winding alignment, electrode consistency, and battery safety performance. Any deviation in strip width or edge quality may increase the risk of defects such as misalignment, burr formation, or potential short circuits during battery assembly.
During high-speed slitting, substrate wandering can result in inconsistent strip widths, while unstable tension may cause wavy edges, burrs, or poor cutting quality. Arise’s Web Guide System ensures accurate electrode centering before the slitting unit, maintaining stable material positioning and improving cutting precision. The CK-2000A width measurement system can be integrated into the slitting process to monitor the width accuracy of each slit strip in real time, helping manufacturers detect deviations quickly, improve process control, and ensure consistent electrode quality.
Case Studies of S1000 Pro Web Guide Systems for Lithium Battery Industry
Inner Mongolia Dongyangguang Forming Foil Co., Ltd. introduced the Arise S1000 Pro high-performance servo web guide system on its lithium battery coating line. During coating, the electrode substrate is prone to wandering at high speeds, causing misalignment between front and back coatings. The S1000 Pro detects edge position in real time through high-precision sensors and drives servo motors for precise correction, ensuring stable web path and coating alignment. After implementation, the system effectively reduced coating scrap from wandering and improved electrode yield and consistency.
