Copper is 70% the weight of lead, but sixteen times as conductive as lead. Hence, the specific energy of lead-acid battery was increased up to 35–50 Wh kg −1 in contrast to conventional lead-acid batteries. Interestingly, this substrate has the potential to be used as a bipolar substrate for lead-acid batteries.
Novel designs evaluated for bipolar batteries include diverse categories of substrate materials such as metals, carbons, ceramics, polymers and composites along with their different designs and manufacturing techniques. 3. Bipolar lead-acid battery 3.1. Fundamentals of bipolar configuration
Future of bipolar lead-acid batteries. Despite lead-acid production facilities being quite appealing in terms of scale, cost, and recycling; low energy density positions the lead-acid battery at the bottom of the Ragone plot of electrochemical systems.
Despite those drawbacks, lead sheets as a substrate did feature in several bipolar battery designs at a laboratory scale in the past. Okada suggested welding a calcium lead alloy sheet for the negative side to an antimonial lead alloy sheet for the positive side of a bipolar substrate.
Each bipolar electrode consisted of the lead infiltrated metal matrix as substrate, which had been oxidised to lead oxide on the positive side, and a layer of lead or lead alloy was present on the negative side. No attempt was made to describe the surface of each electrode in detail.
He suggested the use of high aspect ratio particles for longer unbroken electrical paths in the composite substrate. Those mechanically robust plates showed overall electrical conductivity greater than 1 S cm −1, which was suitable to be used as a bipolar electrode in lead-acid batteries.
