“…The low cost makes lead-acid batteries commercially significant, but its main limitations are considered to be the low dynamic charge acceptance, as well as limited specific energy [2]. To address these issues, many additives to the negative and the positive electrodes have been proposed [3,4]. In addition, additives to the electrolyte [5] are considered as prospective for improving the performance of lead-batteries.…”

During the operation of the negative electrode, some critical processes take place, which are limiting factors for the operation of lead–acid batteries. To improve the efficiency of the negative active material and minimize these processes, external application of multivector field is proposed. Two applications of the multivector field are studied: during negative paste preparation and during formation. It is established that, when applying multivector field during negative paste preparation, the chemical processes proceed more efficiently. The results are better phase composition and crystallinity of the cured paste, thus increasing the capacity of the consequently built lead batteries by 12% on average. The application of a multivector field during the formation of negative active materials in lead batteries has a positive effect on the skeletal structure, the size and shape of the Pb crystals. This ensures longer service life, which is confirmed by the 17.5% Depth of Discharge continuous tests on 12 V/75 Ah batteries. The batteries formed under the influence of external multivector field showed 20% longer cycle life. Based on the experimental result, a most probable mechanism of the influence of the multivector field on the chemical and electrochemical processes in lead batteries during negative paste preparation and formation of negative active masses is proposed.

“…With a focus on energy shortage issues in real-world applications and environmental concerns, the electrochemical energy storage system of batteries has gained more attention in recent years. − To meet battery requirements, the lead-acid battery (LAB) has gained more consideration because of its low manufacturing cost compared to other battery systems. − In addition, it possesses long cycle life with significant performance, and it can be effectively recycled (97%) at end-of-life . A LAB is constructed with positive lead dioxide (PbO 2 ) electrodes and negative lead (Pb) electrodes in series separated by separators including electrolyte solution.…”

In this present investigation, we applied an eco-friendly bacterial cellulose (BC) membrane along with a polyethylene (PE) separator as a separator for lead-acid battery systems. The key factor of the research is to lower the cost of the lead-acid battery by introducing the BC membrane along with a thin PE separator. The specific surface areas of the BC membrane and the PE separator were 46.72 and 35.89 m2 g–1, respectively, with high porosity, which can enhance the electrolyte uptake and movement. The identified pore sizes of the BC membrane and the PE separator are 13.67 and 56.18 nm, respectively. The closely arranged microfibrils in the BC membrane with the smaller pore size can uptake a high amount of electrolyte, and it can hold it for a long period with the hydrogen interactions. In addition, the BC membrane and the PE separator exhibited higher thermal stabilities. The water uptake property of the BC membrane is 130% at 30 °C, which results in considerable electrolyte uptake. The ion exchange capacity of AGM, PE separator, and BC membrane are ∼0.0, ∼ 0.0, and 0.127 meq/g, respectively. The higher IEC is attributed to the presence of hydrophilic functional groups in the BC membrane, which increase the ion transportation in the membrane. The ion conductivity of the BC membrane is considerably higher than those of the AGM and PE separator. The charge and discharge performances of the AGM and BC-PE battery systems were analyzed using lead-acid battery cells. The exhibited discharge performances of both battery systems were considerably similar at 0.1 and 0.2 A discharge current. The final discharge capacities of the AGM battery and the BC-PE battery were 0.96 and 0.94 Ah, respectively, at 0.1 A under identical conditions. A considerable cyclic stability was observed in the BC-PE battery system during long-term operation. From our experimental analysis results, a cost-effective hybrid combination of a BC membrane along with a PE separator can be considered as an efficient separator for lead-acid battery systems.

“…In addition, the active material of positive electrode is inferior in mechanical strength and tends to soften and fall off. Therefore, many efforts have been devoted to add an additive to the positive lead paste to improve the performance of the positive electrode plate, various types of additives are broadly divided into three categories: conductive additives (mostly carbon materials and anisotropic graphite) [6][7][8], inorganic additives (mostly metal oxides) [9][10][11], and organic and organic polymers (including various fibers and binders) [12][13][14]. Although many reports have focused on the use of additives to increase the utilisation rate of positive active materials, there remain challenges to remarkably improving the performance of the positive materials.…”

Pb (PGP) composite material, which was used as a positive electrode to study its electrochemical performance. The scanning electron microscopy images of the electrochemically treated graphite/Pb conductive substrate show that the substrate possesses a three-dimensional porous structure. The active lead is uniformly deposited on the surface of the graphite/Pb substrate, which ensures the stability of the electrode structure and avoids collapse. The cyclic voltammetry (CV) results show that PGP composite has high conductivity and contains multiple redox peaks in different potential intervals. By analysing the CV diagram, the charge-discharge voltage is set at 2.2 V, which shows that the initial specific capacity of the battery can reach 218.2 mAh/g. After 200 cycles, the capacity still reaches 191.4 mAh/g, and the capacity retention rate is 87.7%. These values indicate that the battery composed of the novel graphite/Pb composite has a high initial specific capacity and good stability.
