14. Contactless battery diagnostics A simple, high-throughput, and nondestructive diagnosis on the state of charge (SoC) and defect detection using atomic magnetometers.

This novel diagnostic method identifies hot spots of charge storage Weak transient internal currents (μA) are measured to infer state of charge

This research offers a low-cost, non-destructive technique for quickly screening batteries for local defects. *Source: PNAS Research Group: Geoffrey Z. Iwata, Johannes Gutenberg-Universität Mainz; Alexej Jerschow, New York University
