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
For example, the conductive thermoplastic material filled with carbon composite has been used as the bipolar substrate for Bipolar Pb- Acid Batteries . In the positive plate of the bipolar substrate side, Teflon was coated to prevent the oxidation of the carbon composite.
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.
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.
Bipolar sodium-ion batteries are believed to outperform conventional monopolar sodium-ion batteries. The performance of the bipolar sodium-ion Battery critically depends on the choice of the bipolar substrate, active electrode materials, electrolyte, and thickness and form factor of the cell.
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.
