Abstract: A method for non-invasive characterization of an electrical charge storage device such as a lithium battery, containing lithium ions or lithium metal, the method comprising. The method includes the steps of a) providing at least one electric charge storage device; b) measuring a magnetic field generated by the at least one electrical charge storage device using at least one magnetic field sensor positioned in electromagnetic communication_to the electrical charge storage device; c) acquiring magnetic field data; and, d) determining the condition of the at least one electrical charge storage device using the magnetic field data. The method is operable and effective without magnetic shielding from external magnetic fields, including Earth's magnetic field.

Abstract: A device and a method of using the device to detect flaw and defects in carbon fiber laminates. The device contains an electromagnetic inductive coupling flaw detection for carbon fiber laminates with an excitor-detector operated with alternating current, an impedance matched RLC circuit and a vector-network-analyzer. The device can generate a 2-dimensional or a 3-dimensional representation to indicate a flaw location in a carbon fiber laminate.
