Analyzing Metal Contamination on Automotive Lithium-Ion Batteries

Rechargeable (or secondary) lithium-ion batteries used in electric and hybrid vehicles can overheat or even ignite during routine operation. This fire hazard has been strongly linked to metal contamination during the battery’s manufacturing process, which has the potential to lead to an electrical short circuit.

Due to this risk, thorough contamination analysis is a critical part of lithium-ion battery technical cleanliness inspections.

However, conventional analytical methods have limitations. For example, methods like gravimetric analysis can identify the total mass of detected contamination, but is unable to measure the size of each particulate, leaving the full extent of the contamination unknown.

In addition, a large number of test samples need to be inspected, and the conventional process of using a standard microscope is slow, making the workflow time consuming. And when a stereomicroscope is used for this type of analysis, the contamination detection capability is relatively low, resulting in less reliable data.

Evident’ Solution

The EVIDENT CIX100 technical cleanliness inspection system solves the challenges of conventional technical cleanliness techniques, making it ideal for analyzing metal contamination in lithium-ion batteries.

The EVIDENT CIX100 system is a high-performance industrial microscope with dedicated, flexible software. It can acquire an image of contamination in a lithium-ion battery while classifying and measuring the size of individual contaminant particulates.

Its combination of optimized contamination analysis and user-friendly workflows enable test samples to be inspected reliably and quickly while minimizing variation between different users.

Evident' high-quality industrial objectives facilitate the detection of microscopic contaminant particles between 2.5 µm and 42 mm in size.
