Abstract : A battery electrode fatigue simulator having a frame which supports therein a pivotal and a stationary beam. The pivotval and a stationary beam. The pivotal and stationary beam secure therebetween an electrode plaque which is to undergo the fatigue simulation. Also mounted to the frame is a rotatable cam of predetermined dimension which acts upon a cam follower forming part of the pivotal beam thereby causing cyclic movement or displacement is transferred to the plaque as a cyclic stress in tension. Measurements are made of the displacement of the pivotal beam as well as resistance of the plaque during the application of the cyclic stress. The cyclic displacement versus resistance relationship is representative of the fatigue a battery electrode will undergo during actual battery operation.
