Abstract

PURPOSE:To simply form core-metal exposed parts with a given width in a netative plate, and enhance the strong discharge characteristic of a battery by providing cuts on an active material layer formed by applying a past to a porous core metal, and giving ultrasonic vibration between these cuts. CONSTITUTION:A paste 2, which is prepared by adding a reinforcing synthetic resin fiber to an active material, a conductive material and a binding agent, is applied to a porous core metal 1 which is provided with belt-like non-porous or lowly porous parts. After the core metal 1 coated with the paste 2 is dried, cuts 3 are provided in both surfaces of an active material layer 2' on core-metal exposed parts 1' with a given angle by use of a rotating blade. The surfaces of the active material layer 2', except the exposed parts 1' of a non-formed plate, is pressed with a pressing plate 4. Following that, vibration is given to the surfaces of the layer 2' by making an ultrasonic vibrator to touch the surfaces, thereby the active material layers between the cuts 3 being pulverized and removed to make the exposed parts 1' to be exposed. By the means mentioned above, the exposed parts 1' are efficiently provided in a pasted negative plate, and the large-current discharge characteristic of a battery can be easily improved.
