Principle behind advanced battery scanning

The procedure works by mapping the magnetic properties of the battery in 2D or 3D. The maps are sensitive to the physical distribution of materials inside the battery and their conduction properties. Moreover, the technique can detect changes in the electrode chemistry that occur as the battery is charged and discharged, or if it is damaged. The technology will provide pathways to:

  • Identify common failure mechanisms and defects in batteries in less than a minute.

  • Detailed quality control in battery manufacturing.

  • Significantly shorten the development cycle for safe, next-generation, energy-efficient batteries.

  • Screen batteries for integration into devices.

  • Group cells for modules.

  • Repurposing cells.

  • Screen batteries for shipping.

  • Enable fast and integrated technologies to monitor the state of batteries ‘in the field’.

  • Quickly test state of charge (SOC) and state of health (SOH) of used batteries.

  • Allow a rapid assessment of the performance of new battery and electrolyte materials in a completely noninvasive fashion.

The speed, sensitivity, and non-destructive character of our MRI-based technique represent game-changers in this field.
