Method and device for detecting abnormality in alignment of battery cell type electrodes

A device for detecting an abnormality in battery cell type electrodes, the device comprising:

• an image acquisition apparatus configured to acquire a 3-dimensional image by imaging a specimen including one or more battery cell type electrodes;
• an image determination apparatus configured to determine an arrangement state of the electrodes of the specimen by processing the 3-dimensional image as an input to one or more determination models comprising a deep learning-based determination model or a rule-based determination model;
• and
• an electrode state determination apparatus configured to detect an abnormality in the electrodes of the specimen based on determination results for each of one or more determination models,
• wherein the one or more determination models is configured to extract electrodes from a plurality of tomography images included in the 3-dimensional image, extract endpoint positions for each of the extracted electrodes, and determine the arrangement state of the electrodes based on endpoint positions of pairs of electrodes, and
• wherein the arrangement state includes at least one of whether an electrode alignment is abnormal, whether an electrode is omitted, whether electrodes are duplicated, and whether an electrode is deformed.
