Conclusions The titanium substrate grid composed of Ti/SnO 2 -SbO x /Pb is used for the positive electrode current collector of the lead acid battery. It has a good bond with the positive active material due to a corrosion layer can form between the active material and the grid.
In a bipolar lead/acid battery, the role of the substrate is paramount. The substrate serves as an intercell connec- tion and as a support to active materials. It provides seals between and isolates electrolyte in individual cells.
He suggested an effective sealing method for a conductive substrate to the battery housing. Applying an oxygen impermeable protective coating along the deoxidized edges of the bipolar plate, which (coating) had the potential to be joined with the battery housing material, could produce an electrolyte-tight seal.
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.
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.
