| Abstract Scope |
An anode and cathode quality system based on modal analysis has been developed. The modal detection system finds the resonances of the item tested by measuring the movements of the item caused by an input force from a hammer or shaker. The modal method is verified by measurements and modelling of anodes and cathodes to find cracks and the elastic property, Youngs Modulus (YM). Measurement times around 60 s/item can be achieved. For an inline station to measure YM and find crack plane orientations, the resonances need to be identified by mode shapes. The method has a huge potential of detecting items with cracks that can cause unstable cell operation and early cathode failures. In addition, the modal test can provide feedback to production plants of anodes and cathodes to produce those items which are closest the reference spectrum of resonances from a crack free homogeneous product. |
