Patent ID: 8369482

Claim:
An apparatus for inspecting electrodes of a battery, the apparatus radiating 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 inspecting an arrangement state of the anodes and the cathodes, the apparatus comprising: a first X-ray source part for radiating a first X-ray beam onto the battery; a first detector for detecting the first X-ray beam having transmitted through the battery; and a control unit for receiving an image of the battery output from the first detector, calculating a step difference between each anode and each cathode, and then inspecting an arrangement state of the anode and the cathode, wherein the first X-ray source part radiates the first X-ray beam in a direction parallel with a stacked surface of the anode and the cathode of the battery so that the first X-ray beam is radiated at a predetermined angle of inclination in a direction horizontal to a ground surface.
