Abstract:
A current collector assembly, such as for a bipolar lead acid battery, can include an electrically-conductive silicon substrate and a frame bonded to the electrically-conductive silicon substrate. The substrate can be treated or modified, such as to include one or more thin films which render a surface substrate electrically conductive and electrochemically stable in the presence of a lead acid electrolyte chemistry. An interface between the frame and the electrically-conductive silicon substrate can be hermetically sealed. In an example, the frame can provide an edge-seal ring configuration. In an example, a casing assembly can include a spacer bonded to the substrate, along with a casing segment and a thermally-conductive rib, the spacer isolating the thermally-conductive rib from the electrically-conductive silicon substrate electrically.

Abstract:
Apparatus and techniques are described herein for providing a bipolar battery plate such as can be included as a portion of an energy storage device assembly, such as a battery. The bipolar battery plate can include a silicon substrate. A first metal layer can be deposited on a first surface of the rigid silicon substrate, and a different second metal layer can be deposited on a second surface of the rigid silicon substrate opposite the first surface. The first and second metal layers can be annealed to form a first silicide on the first surface and a different second silicide on the second surface of the rigid silicon substrate.

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.
