The battery cell and its components are the centerpieces of the final electric battery that will power an electric vehicle (EV). Learn more about how using the right inspection systems can help to detect and monitor component and product quality.
Powerful battery electrodes and the separator film are indispensable components of the lithium-ion battery. The coated electrode materials for cathodes and anodes must meet the highest requirements in terms of energy efficiency, storage density, and of course, safety. The aluminum and copper-coated electrode plates must have an extremely smooth and closed coating where required.
Another component of the battery cell with extreme quality requirements is the lithium-ion battery separator film. This film divides the anode from the cathode to enable lithium ions to be exchanged. The film is also an essential safety element that will prevent a short circuit in the battery and plays a significant role in cell speed and service life. The film must possess flawless porosity and uniformity for use in a battery cell but also have solid chemical stability and be resistant to heat and tearing.
Cell components inspection system for reliable quality assurance
The SMASH inline inspection system from ISRA VISION offers a comprehensive and reliable quality assurance solution detecting and classifying all surface defects. The inspection system checks electrode material quality for damage such as streaks, holes, impurities, and air bubbles. All relevant sources of error can directly be eliminated. SMASH can also be utilized in the classification of production defects in the PVDF fluoroplastic coating used for separator film for holes, stains, oil, water drops, and scratches. This intensive inspection is possible with high-resolution 8k and 16k cameras and multi-scan technology with up to three simultaneous scans.
