Bipolar plates are one of the key components of vanadium redoxflow batteries. They electrically conduct and physically separate adjacent cells in series and provide structural support to the stack.
Novel designs evaluated for bipolar batteries include diverse categories of substrate materials such as metals, carbons, ceramics, polymers and composites along with their different designs and manufacturing techniques. 3. Bipolar lead-acid battery 3.1. Fundamentals of bipolar configuration
A manufacturing method developed by Michel Saakes et al. assigned to TNO, Netherlands, describes the bipolar plate fabrication as well as the battery assembly process in detail. Initially, the polymer composite substrate was thermally pressed, followed by a ‘surface activating treatment,’ and after that, the substrate was lead-plated.
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.
One of the most important components of a bipolar lead-acid battery is the bipolar plate. The following demands have to be fulfilled by the materials used for the bipolar plate: In this paper several design principles for bipolar lead-acid batteries will be presented.
The bipolar electrode assembly generally consists of a thin, electronically conductive substrate, with positive active material (PAM) applied to one face of the substrate, and negative active material (NAM) applied to the opposite face. Single-sided (monopolar) electrodes, along with endplates, constitute the end section of the bipolar battery.
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.

Bipolar batteries are Li ION batteries that consist of stacked electrodes connected in series. The active material for the cathode and the active material for the anode can be deposited on the common electrode carrier, which consists of two different metals.
The active materials of a battery are the chemically active components of the two electrodes of a cell and the electrolyte between them. A battery consists of one or more electrochemical cells that convert into electrically energy the chemical energy stored in two separated electrodes, the anode and the cathode.

On the other hand, the stack components are mainly contributing to the costs with higher power/energy ratio. 82 Since the BPP is a repeatable component in a VRFB stack it is thus partly responsible for the arising areal costs of the reaction unit. 73 Some publications indicate that the share of BPP costs is roughly 2%–8% of the total capital costs of a VRFB system with …
