X-ray particle contaminant analyzer
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.
Approximately 5 minutes, the inspection of metal particle contaminant in a range equivalent to A4 size can be completed with a transmission X-ray image.
Metallic metal particle contaminant in fine powder with a small atomic number can be detected by putting an appropriate amount in a bag and spreading the particles thinly.

Measurement of coated cathode and anode plates enables production management.
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.
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.
