Higher capacity and output of lithium-ion rechargeable batteries requires more precise production processes. The risk of heat and ignition caused by contamination metal foreign matters has increased. For that reason, detecting a foreign matter early and identifying the type of the foreign matter and its source largely contributes to improvement of the yield.
Hitachi High-Tech offers an X-ray in-line foreign matter inspection system, which detects foreign matters in production lines instantly, and X-ray particle contaminant analyzer EA8000A, which enables both rapid detection and elemental identification of foreign matters.
