Abstract
Methods and systems are provided for manufacturing a bipolar plate for a redox flow battery. In one example, the bipolar plate is fabricated by a roll-to-roll process. The bipolar plate includes a non-conductive substrate that is coupled to a negative electrode on a first surface and coupled to a positive electrode on a second surface, the first surface opposite of the second surface.
Claims20
A method for fabricating a bipolar plate, comprising;
- arranging a flexible substrate between a first roller and a second roller;
- moving the flexible substrate in a direction from the first roller towards the second roller;
- coupling a top surface of the flexible substrate with a first conductive material as the flexible substrate is moving;
- coupling a bottom surface of the flexible substrate with a second material as the flexible substrate is moving;
- bonding the first conductive material and the second conductive material to the flexible layer and forming the bipolar plate, the flexible substrate sandwiched between the first conductive material and the second conductive material, as the flexible substrate is moving from the first roller to the second roller;
- and
- collecting the bipolar plate onto the second roller.
