World’s first tomographing of interior of lithium battery

A lab team, led by Professor Kawamura, in Institute of Multidisciplinary Research for Advanced Materials Tohoku University, succeeded in tomographing the interior of the lithium battery by using the MRI technique, which is widely used in medical fields. This is first in the world.

The success in tomographing the interior of the lithium ion battery enables one to detect the interior destruction and the deterioration of the lithium ion battery. This will contribute to improvement of the safeness of the lithium battery and development of the battery anti-deterioration technology.

While the medical MRI is capable of detecting hydrogen atomic nuclei (protons), it has been difficult for the MRI to detect lithium ions. The lab team succeeded in measuring MRI images of the hydrogen protons. Thus, the lab team clearly showed that the MRI technique could be used for diagnosing deterioration of the lithium battery.

NEDO is carrying out the project of developing the most-advanced electric power storage technology in use for automobiles toward commercialization of next-generation clean energy automobiles, such as plug-in hybrid vehicles, electric vehicles, and fuel cell vehicles. The project is called “Li-EAD project”.
The study by Professor Kawamura, et al has been made as part of the Li-EAD project.
