Electrode is a key component of many energy storage and energy conversion devices such as batteries and fuel cells. Defects in electrodes can significantly influence device performance and reliability and thus need to be monitored and eliminated during the electrode manufacturing process. Advancements in in-line metrology, computer vision, and machine learning have enabled the development of integrated hardware-software systems for automated defect detection and diagnostics. While several manufacturing domains have published defect datasets to support such efforts, publicly available datasets specific to electrode coating processes are not available. To fill this gap and support research on defect detection for automated coating processes, we present CoatingVision, a comprehensive dataset of slot-die coating images with labeled defect types. This dataset supports a diverse range of image recognition tasks, including defect segmentation, defect detection, and multi-label classification. It includes high-resolution images with associated labels for common defects such as surface cracks, delamination cracks, pinholes, and unclassified defects. To facilitate benchmarking and reproducible research, CoatingVision is packaged with an open-source codebase that enables comparative evaluation of AI models and hyperparameter configurations. The dataset has been meticulously curated to ensure high quality and consistency, providing researchers with reliable data for training and evaluating computer vision models. With over 2,200 image samples under various processing conditions, CoatingVision offers a robust foundation for developing automated defect detection systems. It promotes deeper insights into defect formation in coating manufacturing processes, which can be used to advance various coating-related applications including batteries and fuel cells.
