  • Electrode inspection device for battery and method of the same
    Patent number: 8369482
    Abstract: The present invention relates to an apparatus and method for inspecting the electrodes of a battery, which inspects the arrangement state of anodes and cathodes in the battery in a non-destructive manner (using X-rays). The apparatus radiates X-ray beams onto a battery in which a plurality of plate-shaped anodes and a plurality of plate-shaped cathodes are alternately stacked and inspects an arrangement state of the anodes and the cathodes. The apparatus includes a first X-ray source part for radiating a first X-ray beam onto the battery. A first detector detects the first X-ray beam having transmitted through the battery. A control unit receives an image of the battery output from the first detector, calculates a step difference between each anode and each cathode, and then inspects an arrangement state of the anode and the cathode.
