Title
(EN) SILICON CURRENT COLLECTOR FOR LEAD ACID BATTERY
(FR) COLLECTEUR DE COURANT AU SILICIUM POUR BATTERIE PLOMB-ACIDE
Abstract
(EN) 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.
(FR) L'invention concerne un appareil et des techniques pour produire un ensemble plaque de batterie comprenant un collecteur de courant au silicium. Le collecteur de courant au silicium peut comporter des ouvertures. Une couche de plomb ou une couche d'alliage de plomb peut être formée sur le collecteur de courant au silicium. Un ensemble batterie monopolaire peut être produit, par exemple comportant des ensembles plaque de batterie monopolaire comprenant des collecteurs de courant au silicium. Le silicium peut être un silicium de qualité métallurgique conducteur, par exemple coulé et découpé pour produire des substrats de collecteur de courant individuels.
