Abstract
Abstract Electrode-separator unit, designed particularly for high energy density batteries, comprising an organic or inorganic honeycomb matrix, preferably formed of a porous ceramic material, a first electrode material such as zinc positioned in some of the cells of the honeycomb matrix and a second electrode material such as silver positioned in other cells of the honeycomb matrix, such electrode materials being separated by the honeycomb wall; and a battery containing such electrode-separator unit.
