Battery separator with a conductive layer for extending the cycle life of a battery

摘要

A battery separator for extending the cycle life of a battery has a separator and a conductive layer. The conductive layer is disposed upon the separator. The conductive layer is adapted to be in contact with the positive electrode of the battery thereby providing a new route of current to and from the positive electrode.

主权项

1. A battery separator for extending the cycle life of a lead-acid battery comprising:
a separator having ribs with tips; and a conductive layer being disposed only on said tips, said conductive layer being made of a conductive material being selected from the group consisting of lead, gold, antimony, arsenic, tin, and combination alloys thereof, or carbon fibers, graphite, carbon nanotubes, and buckyballs; whereby said conductive layer being configured to directly contact a positive electrode of the lead-acid battery thereby providing a route for current to and from said positive electrode when the conductive capability of a positive electrode conductor deteriorates, wherein the shape of said ribs being straight, angled or waved.
