Lithographically printed cells

There are disclosed cells (100, 200, 300, 444) which include one or more layers formed by a lithographic printing process. The layers may be formed by offset lithographic printing. In one embodiment, a cathode substrate (110) is coated with a silver current collector layer (115) and a graphite layer (120). A paste (170) of manganese (IV) oxide and carbon is deposited over the graphite layer (120). A membrane (180) separates the anode and cathode. An anode substrate (140) is coated with a silver current collector layer (145) and a zinc layer (150). The lithographic inks include a resin to provide thixotropic properties. The cells (100, 200, 300, 444) can be manufactured more rapidly than by screen printing, while using less ink than screen printing.
