Abstract
Apparatus and techniques such as can include a sealed bipolar battery assembly are described herein. For example, the battery assembly can using two or more sealing techniques, such as to provide a liquid-tight assembly. A sealed current collector assembly can be provided, such as by fitting compressible plastic seals to one or both side of a current collector. An adhesive seal can be applied to an edge or perimeter of the current collector. A plastic seal assembly can be used to anchor the seals or to provide an additional layer of leakage protection should electrolyte seep under hydrophobic plastic seals. Current collector assemblies including stackable casing frames can be assembled to provide a rigid casing. These casing assemblies can be stacked on top of one another to form bipolar cells comprising the battery assembly.
