Abstract:
A method of producing a battery construction comprising a ceramic separator having a honeycomb structure with two opposed faces between which cells run lengthwise of the honeycomb and are separated by porous walls, at least a portion of the cells having internal positive and negative electrodes positioned in part at least within the honeycomb structure and a portion of each such cell having sealing material that extends inwardly from a face of the structure and an electrode member of smaller diameter than the cell extending into the cell from the opposite face, the method comprising forming an extrudable mixture of ceramic material precursors, extruding the mixture through a die designed to produce an elongated body having open cells running lengthwise of the body with thin walls defining and separating the cells, cutting a section having opposed faces from the extruded, elongated body, sealing off selected cells with material extending into the cells from one face, and introducing active material into the sealed off, selected cells and positioning an electrode wire in each of these sealed off, selected cells from the opposite face.
