Abstract
Apparatus and techniques are described herein for providing a battery plate assembly including a silicon current collector. The silicon current collector can include apertures. A lead layer or lead alloy layer can be formed on the silicon current collector. A monopolar battery assembly can be provided, such as including monopolar battery plate assemblies comprising silicon current collectors. The silicon can include a conductive metallurgical grade silicon, such as cast and cut to provide individual current collector substrates.
