Highlight

Along with measures for reducing the load on the environment, development of fuel cells and electric vehicles using rechargeable batteries has proceeded with the aim of reducing CO2 emissions. For the LIBs, fuel cells, and other components used for this purpose, greater safety and quality is required particularly in automotive applications. Metal particle contamination in batteries is one cause of degrading reliability and quality, making this an important aspect of quality control. To satisfy this new demand, Hitachi High-Tech Science has developed X-ray technology and equipment to detect and identify fine metal particles.
