An electrode for primary or secondary electric battery comprises an electrically conducting substrate 5,6 supporting an active mass 2,3 which is covered by an electrolyte permeable separator 1. An electrode suitable for automatic production and bearing the active mass 2,3 retained effectively against the support is obtained by providing the active mass in the form of a plurality of strips 2,3 which are retained under pressure by the separator layer 1 said layer being effectively secured to the substrate between the strips of active mass. The electrode may be bipolar having positive and negative masses 2,3 on its respective faces. In a battery carried out of such electrodes the strips 2,3 of active mass are parallel and have an approximately triangular cross section and on adjacent electrodes of opposite polarity the strips of active mass are displaced a half pitch with respect to one another. The electrodes are mutually sealed around the periphery by means of a sealing packing. in the method for producing the electrode the active mass is placed as a plurality of parallel strips on a ribbon of the substrate whereafter the separator is placed upon the strips and secured to the substrate whereupon the ribbon is cut into individual electrodes. <IMAGE> |
