<p>Described is a method for manufacturing a bipolar plate (10) for, for instance, a bipolar battery. According to the present invention, a negative plate (112) is manufactured by applying a suitable paste (121) in a metal grid (120), and a positive plate (113) is manufactured by applying a suitable paste (123) in a metal grid (122). The pasted plates (112; 113) are formed, and arranged on opposite sides of a suitable platelike substrate (11). The substrate (11) is thermally pressed, then a surface activating treatment is carried out, and thereafter the substrate (11) 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 (11) can be roughened, and the plates (112, 113) can be pressed against the substrate (11) by utilizing a compressed glass fiber mat (21).</p> |
