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.
Mrotek et al. have described a double-layer structure for use as a bipolar lead-acid battery substrate. Embedded in a suitable binder, the first layer contained conductive transition metal oxide and the second layer contained conductive carbon layer.
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.
The term “bipolar battery” refers to the presence of bipolar electrodes inside a battery module. Theoretically, this technology may be applied to batteries with different chemistries. In reality, among all the various bipolar batteries, only lead-acid battery modules have reached the commercial production stage.
However, from Reichman et al.’s patent, it was evident that it would increase the resistivity of the bipolar plate up to 9.2 Ω m, which was unacceptable to be used as a bipolar substrate in the lead-acid battery. Therefore, Partington addressed those issues related to resistivity, porosity, particle size distribution, and manufacturing process.
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.

Bipolar lead/acid batteries offer the possibility of increased energy and power density. This paper presents the results of a theoretical and experimental study into the performance of a bipolar construction. A model that calculates the ohmic losses in a bipolar lead acid battery has been used to predict the cell voltage during discharge. The ...
More active materials can be incorporated into a limited battery case for higher capacity storage. [9] Consequently, capacity, cost, and size of the rechargeable batteries are improved simultaneously. For example, the first commercial lithium‐ion battery (LIB) was assembled by LiCoO 2 cathode and graphite anode. Despite of using identical materials as before, the …
We have briefly reviewed different bipolar lead-acid batteries; describing their assembly structure, material composition and relative merits along with demerits.

Attempting to develop a composite substrate for a bipolar lead/acid battery, more than 120 ceramic materials were screened. About 60 of them having a conductivity greater than 10 Ω −1 cm −1 and cost less than US$ 1/g were tested. Test methods and devices were developed to examine the chemical and electrochemical stability of the filler materials, oxygen …

Potential distribution has been calculated by some authors in the standard case of grid design but not for bipolar design. Morimoto et al. [5] presents a model where potential distribution is calculated from grid resistivity and experimental polarisation data. After calculating the potential distribution for one state of charge, he simulates the whole discharge by adjusting …
In general, thicker active material bipolar electrode''s specific capacity and cycle life are very poor owing to its low bonding strength between the active material and the substrate and the diffusion rate of the sulfuric acid electrolyte inside the active material. In this paper, we synthesize a novel attached and porous lead/graphite composite electrode for bipolar lead …

TSB co-founder, CEO and president Nick Busche told Batteries International on February 1 that around $33 million has been invested in setting up …
A bipolar lead-acid battery shown in FIG. 1 uses a different approach. An external case 100 encloses a series of parallel bipolar plates 104. Each bipolar plate 104 is a solid sheet, with its positive side covered by positive active material 106 and its negative side covered by negative active material 108. Bipolar plates 104 partition the battery into a series of cells …
We recently wrote about the various improvements in lead acid battery technology since its invention in 1860. While its versatility, power, and affordability are still unmatched, the lead acid battery is still a little overweight. …
The comparison demonstrates that with batteries of the same weight, bipolar lead-acid batteries are capable of providing more instant power (W), while lithium-ion single electrode modules store more electrical energy (Wh).
The bipolar battery essentially moves the series connections inside the cell. This brings a number of advantages and significant challenges. This is shown very clearly in the Toyota battery technology roadmap [1].
