Chemists Develop MRI-Like Technique to Detect What Ails Batteries (IMAGE)
Caption
A team of chemists has developed an MRI-based technique that can quickly diagnose what ails certain types of batteries -- from determining how much charge remains to detecting internal defects -- without opening them up. Above is an illustration of measurement setup showing the cell and the holder with the detection medium (water in this case), and (d) showing both inserted within the magnet bore of an NMR magnet.
