X-ray inspection system

Inspection of buried metal particles in opaque products such as electrode plates that cannot be detected with visible light is possible. We offer inspection systems that meet the inspection width and line speed requirements, etc. In combination with the EA8000A X-ray foreign material analyzer, efficient inspection and analysis can be performed.

Quality management

We also contribute to solve the key issues related to lithium-ion batteries: "Quality" and "Yield."

We offer a lineup of electron microscopes that are optimal for quality control, from scanning electron microscopes that support large samples to desktop electron microscopes. Our EA8000A X-ray particle contaminant analyzer has the world's highest level of foreign object detection capability for detecting and analyzing foreign object in lithium-ion batteries with high throughput. We also offer one-stop services for evaluation and analysis of lithium-ion batteries in cooperation with our contracted measurement service company Japan Testing Laboratories, Inc. (JTL).

Quality management

Foreign Matter Inspection

We support building a production system that can reliably provide safe and secure lithium-ion rechargeable batteries.

Hitachi High-Tech offers a foreign matter analyzer that detects and analyzes metal foreign matters with high throughput as well as an in-line foreign matter inspection system that realizes 100% inspection in production processes. We support building a production system that can reliably provide safe and secure lithium-ion rechargeable batteries.

Lifecycle management

Towards a comprehensive data management service based on the residual value analysis and management of lithium-ion batteries

Hitachi High-Tech Corporation has developed a method of Diagnostics of Battery Degradation that instantly evaluates the performance degradation and remaining life of lithium-ion batteries during or after use.
By introducing the evaluation method into each process of the production, use, and recycling of lithium-ion batteries for electric vehicles, it can be used as a new data management platform for functions including the “monitoring of individual battery usage status,” the “clarification of remaining performance evaluation at the recycling/reuse phases,” and “visualization of supply-and-demand balance and market value forecasts for battery reuse/refurbish.”
