X-ray particle contaminant analyzer

EA8000A

EA8000A

With the world's highest level capability of X-ray metal particle contaminant inspection, EA8000A detects and analyzes metal particle contaminant in lithium-ion rechargeable batteries with high throughput.

For lithium-ion rechargeable batteries, contamination by metal particle contaminants directly reduce battery performance, safety, and yield rate. Hitachi High-Tech's X-ray particle contaminant analyzer EA8000A is an inspection device that quickly detects and identifies 20μm-class microscopic metal metal particle contaminants that may cause problems in lithium-ion rechargeable batteries. Just selecting inspection conditions and starting measurements automatically execute the process from capturing the X-ray transmission image to detecting metallic metal particle contaminants and identifying its elements. This greatly contributes to failure analysis and inspection at manufacturing sites for lithium-ion rechargeable batteries.

Management of dust particles from manufacturing equipment

By periodically measuring the setup tape, the amount of dust generated by the device and its fluctuations, and the composition of the generated dust are comprehensible, and the device can be managed too.

Contamination by metallic metal particle contaminant

Fe that could not be found by visual inspection of short circuit marks alone is detected. Metallic metal particle contaminant may become mixed during the separator manufacturing process. Even if aging does not cause a problem, repeated charging and discharging may cause a defect.
