Magnetic resonance for metal-ion batteries: from NMR to EPR imaging

The research on metal-ion batteries is the key to improving the performance of the battery. Magnetic resonance, including nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR) with imaging, has gradually become an important technology to study the structure-performance relationship of cathode and anode materials. This paper summarizes the basics of magnetic resonance (e.g., pjMATPASS) and the progress of magnetic resonance research on metal-ion batteries, mostly from our group, demonstrating the important role of NMR, EPR and EPR imaging in the study of metal-ion batteries. This article will help to grasp the important value of magnetic resonance technology for metal-ion batteries research and promote the further development of advanced magnetic resonance technology.
