Abstract
An electrode plate for use in electrochemical cells such as batteries that is formed of multiple layers of electrode material. Each layer is provided with pores through the layer and creases, folds, corrugations, scoring, or the like and is juxtaposed on and electrically connected with the other layers in the plate without intervening layers of opposite polarity. Electrolyte flow by diffusion and/or capillary action takes place within the plate through the pores and between the layers. In an alternative embodiment, a plate is formed of layered grids to which is applied a paste of active material. The grids are then formed into a multilayered plate.
