Disrupts Battery Quality Control / Testing by All-cell Inspection before Shipment.


Our Nondestructive Battery Imaging Diagnostic System visualizes the electric current-density distribution inside batteries, thus enabling nondestructive failure analysis and quality control in all-cells pre-shipment inspections.


By measuring magnetic field and reconstructing the electric current distribution inside batteries, our system visualizes very minute internal deterioration (even before a short circuit occurs) that is undetectable by conventional aging test. Our technology can inspect both lithium-ion and solid-state batteries.


We believe our battery inspection system innovates battery quality control by reducing product risk and even enabling quality grading. We are proceeding with installment of our equipment to battery production sites and would like to work for more clients.

IGS is a deep tech company dedicated to solving human challenges by making the invisible. We are committed to addressing human issues using its core mathematical visualization technology. By consistently aligning our solutions with social challenges, we strive to innovate and continue resolving these issues effectively.


Our technology is based on the wave scattering theory established by our founder Prof. Kimura at Kobe University in Japan. He achieved a global first by analytically solving the inverse problem of wave scattering, which was a longstanding challenge in applied mathematics. The theory is supported by ultra-sensitive sensing technology developed by IGS and applied to many practical fields to “visualize the invisible”.

Our “Nondestructive Battery Imaging Diagnostic System” measures the electric current-density distribution inside batteries, thus enabling nondestructive failure analysis and quality control.


Traditional methods for inspecting rechargeable batteries have proven inadequate, leading to numerous ignition incidents. Pre-shipment inspections often rely on voltage drop tests (aging tests) after charging. Despite passing these tests, many batteries have still experienced explosions, highlighting a growing social concern in recent years.

Using a proprietary calculation theory, IGS visualizes density distribution and short-circuit locations within batteries. Our system measures the magnetic field generated by electric current using an ultra-sensitive magnetic sensor, identifying potential failure points. Since the system applies only alternating current, evaluations are performed without damaging the battery.


Our system automatically measures the battery's magnetic field, calculating electric current using software based on inverse analysis theory. The data is visualized, highlighting areas with irregular electric concentration in different colors, enabling easy identification of potential faults.
