The separator is an essential component of the lithium-ion battery separating the electrodes and preventing them from short-circuiting. If the separator fails. the battery discharges, which can lead to fire or explosion.
The growing demand for lithium-ion battery applications requires defect-free separators and high-quality electrode material. A high-quality separator significantly improves the speed and the lifetime of a battery.
The SmartView® system is placed on the coating and slitting processes in most applications, while the high-speed inspection system ensures support with high-resolution image acquisition of defects including gel, contamination, strips, relief material, cutaways, coating defects, insects, pinholes, folds, foreign particles, and pollution.
AMETEK Surface Vision’s machine vision system has been created to detect and classify separator defects, ensuring battery producers can distinguish non-quality-related optical effects from genuine defects. SmartView’s detection technology reduces the need for manual intervention and can adapt to the huge variety of separator membrane types.
