Abstract

Rechargeable batteries form a key technology for providing portable energy and are used in many applications such as mobile computing, communications, electric mobility, and consumer devices. Complementary techniques are desirable to provide insights into the processes of commercial batteries. Battery diagnostics is essential to rule out manufacturing errors, which can pose serious risks to the public as unexpected fires can occur. Nuclear magnetic resonance and magnetic resonance imaging (MRI) are excellent techniques for the study of complex reactions, flow, and electrochemical processes. It is well known that conductive materials have a strong influence on the propagation, distribution, and distortion of radiofrequency irradiation. A crucial parameter for battery performance is the distribution of electrical current during charge and discharge at different states of charge. Lessons learned with MRI have led to the idea that the magnetic fields around batteries could also be detected and mapped using advanced magnetometer sensors.
