s the electric vehicle (EV) market advances, so does demand for lithium-ion batteries (LIBs). While safety remains paramount, manufacturers must also reduce costs to be competitive. Because electrodes, including cathodes, anodes and separators account for a signifi cant portion of the overall LIB cost, manufacturers must scale production effi ciently while maintaining strict quality standards. To address this, manufacturers increasingly turn to machine vision systems for cell
component inspection. These systems enable better process and quality control while driving down costs, particularly in the critical early stages of production.
THE ELECTRODE CHALLENGE: PRECISION IN ROLL-TO-ROLL COATING
Electrode production begins with roll-to-roll (R2R) machinery, which coats large rolls of material with precision layers to form the anodes and cathodes of a battery. These fi lms undergo further processing, including high-speed
calendaring, to achieve the desired thickness and compressive properties.
However, the high cost of electrode materials, combined with the complexity of this production stage, underscores the importance of minimising waste and ensuring defect-free manufacturing. Machine vision systems have become indispensable in this effort, offering real-time inspection capabilities that help manufacturers meet both quality and efficiency goals.
