Abstract
Described is a method for manufacturing a bipolar plate for, for instance, a bipolar battery. According to the present invention, a negative plate is manufactured by applying a suitable paste in a metal grid, and a positive plate is manufactured by applying a suitable paste in a metal grid. The pasted plates are formed, and arranged on opposite sides of a suitable platelike substrate. The substrate is thermally pressed, then a surface activating treatment is carried out, and thereafter the substrate is lead-plated. That surface activating treatment can be carried out with a corona or, preferably, a plasma. To ensure a good electrical contact, the substrate can be roughened, and the plates can be pressed against the substrate by utilizing a compressed glass fiber mat.
