Predicting the formation of mud cracks in Li-ion battery electrodes during the drying process with in situ X-ray computed tomography

Key Points

• The study aims to predict when cracks form in Li-ion battery electrodes during the drying process.
• Utilized in situ X-ray computed tomography for observation.
• Applied highly sensitive digital volume correlation to detect crack initiation.
• Monitored drying process of electrodes to identify real-time changes.
• Crack initiation was detected at a specific point during drying.
• Findings highlight the importance of drying conditions on electrode quality.
