摘要： Positive ribbon electrodes for primary and secondary cells are produced in a dry process wherein two strips of active material in powder form, preferably comprised of MnO.sub.2, FeS.sub.2, CuO, .alpha.-Cu.sub.2 V.sub.2 O.sub.7, and Li.sub.x MnO.sub.y, are simultaneously rolled and then fed into the gap of a roller mechanism, on opposite sides of an interposed metal net or mesh, to roll coat both sides of the lattice-like carrier strip. After excess mass is stripped off, the finished electrode ribbon has a thickness of less than 0.45 mm and a porosity of more than 24% which, because of its large active surface, is advantageously used in wound batteries incorporating Li or H.sub.2 electrodes.
