Bipolar lead–acid battery for hybrid vehicles

Lead–acid batteries for hybrid electric vehicles and battery electric vehicles

“…In the bipolar design the geometric electrode surface, and therefore the capacity, is limited by the cross-section of the bipolar stack. The current path and cell weight can be minimized, and the current density is very homogeneous across the electrode (Saakes et al, 2005). Although there have been many attempts to develop this design of battery, they have all failed commercially, mainly because of corrosion of the bipolar plate and as a result of insufficient cell sealing.…”

Charging ahead

“…Energy density is improved by using lighter, noncorrosive collectors [2] while the HRPSoC issues are being addressed by adding conductive carbon to the active material to mitigate the sulfation issue.…”

High-performance porous lead/graphite composite electrode for bipolar lead-acid batteries

“…It can realize higher specific energy and longer cycle life owing to its special structure and current conduction model [11,12]. It can realize higher specific energy and longer cycle life owing to its special structure and current conduction model [11,12].…”

“…Figure 1 showed the current conduction between monomer cell in the traditional and bipolar leadacid battery. Thus, the battery can charge and discharge quickly and has longer cycle life and be used for hybrid electric vehicle or pure electric vehicle to hopefully [12]. This can reduce the current transmission distance and electrochemical polarization resistance [13].…”
