A method of diagnosing a conducting structure includes providing the conducting structure in a magnetic field, immersing the conducting structure in a detection medium, or placing a detection medium in the vicinity of the conducting structure, exciting nuclear or electronic spins within the detection medium using a broad-band excitation pulse, receiving an NMR or ESR spectrum from the detection medium, obtaining a frequency distribution of the detection medium, and indirectly measuring internal characteristics of the conducting structure by characterizing frequency changes in the frequency distribution. Conducting structures are analyzed on the basis of changes in magnetic susceptibilities and internal electric current distributions, which may change over the course of a charging/discharging cycle, and a result of degradation and failure of the conducting structure. The conducting structure may be, for example, a battery, a capacitor, a supercapacitor, a fuel cell, or a catalyst material.

System and method for magnetic resonance mapping of physical and chemical changes in conducting structures

System and methods that reconstruct absolute temperature using a multi-nuclear approach. Specifically, the methods and systems utilize independent NMR/MRI information provided by the precession frequency of two different nuclei to reconstruct a map of the absolute temperature.
