There is a distinctive stack configuration of rechargeable batteries, referred to as bipolar electrodes (BEs), that ultimately simplifies the components of rechargeable batteries. A schematic illustration of BEs is displayed in Figure 1c. The cathode and anode slurries are separately coated on both sides of the substrate.
In the case of BEs, the bipolar batteries have a simplified cell configuration and shape because of no use of electric connectors and other accessories. The stacking thickness of all unit cells and the substrate area of a unit cell is used to calculate battery volume. The battery weight is close to the mass sum of all the components.
