Degradation of Lithium Batteries Shown In Real-time (ucl.ac.uk)

hypnosec writes: High-Speed Operando Tomography and Digital Volume Correlation have been used by a University College London-led team to show in real-time how lithium batteries degrade as they are used. Real-time 3D images of active, commercial Li/MnO2 disposable batteries were captured using X-ray computed tomography (CT) and advanced digital volume correlation software. The images formed cross-section time-lapse videos showing the damage occurring on the electrodes inside the battery in real-time.

    "The images formed cross-section time-lapse videos showing the damage occurring on the electrodes inside the battery in real-time."

    Not sure the editors know what words are.

    Super-capacitors are already extremely reliable and affordable, the problem is they can't really store a whole lot of power at present. They are used in some trucking applications in tandem with standard lead acid batteries. Some also have a minor issue with self discharging, but if their capacity could be brought up to battery levels and that self discharge limited they would likely have a major impact on the battery market. They virtually don't degrade (1 million charge/discharge cycles without degradation have been shown), they can charge very quickly and they are very simple (which should make them cheap).
